people will still want to play their old games. hell i started playing chrono cross and ff7 again on my PS3.. i would play my PS2 games (have to dig the ps2 out first!), but Sony decided to say no. if it can be run in software emulation on a COMPUTER, made by people programming for free and for the fun of it, surely Sony could sanction some people to code it on the PS3/4 for chump change. Emotion chip or not. and who cares about some jaggy pixles? you're looking at games made before the 720p and 1080p boom! they're going to look crappy in comparison on a larger TV anyways. you replay old games for the replay value if you still have them.. not to be dazzled by graphics. that's what new consoles are for.

the LEAST they could do is put some converted PS2 games that people actually played in the PSN store.

The problem of compatibility going backward is similar - if not exactly the same - as developers having to re-write code to assimilate their already established design goals onto a completely different - derivative - architecture.

Backward Compatibility is a headache that both designers and developers wish people would just forget about if they want advanced future technology in their hands before every full decade expires into a new one.

So which is it: Advanced Future Technology or, "It's not a big jump but it goes backward, O' loyal customer of ours."

Um, go look in [Settings][Game Settings] and there should be an option to turn on game filtering.

im just saying you cannont just release this system out their people are just now getting use to ps3 kkkk you cannont just do this kkkkk Xd and we appricate it if you can push your creation of the ps4 more longer because people are still loving the ps3 and also economy today is so good as it use to be so thx

So, considering today's chatter around the web, it seems Sony is not including any backwards compatibility on the PS4 (Orbis?). Sony is also not allowing used games to be played on the PS4 (Orbis?). I will keep my PS3 and not get a PS4. I will get a Wii-U too. Maybe an Xbox360 too since I never had an Xbox. Wii-U for the newer games. Plenty of good content on the PS3 and Xbox360. I still have yet to finish many of my PS3 games as it is. Looks like many people will not buy a PS4 or Xbox720 if they do this stuff. I'm still play old games. I have a NES, SNES, N64, Wii, and a launch PS3. With all that, I can play all old games from any Sony or Nintendo system. I think I'm just going to keep it that way and enjoy the classics. I don't need a PS4 anymore. Wii-U is the way to go for me next generation. I'll still have to keep my Wii since the Wii-U can't do Gamecube. Or maybe I'll get a Gamecube and Wii-U instead. I at least appreciate Nintendo's plan to always allow backwards compatibility to the previous generation. That's fair. I love Nintendo and they love me back. Sony is turning into a nameless, faceless, greedy, pushy, fascist brand.

As a gaming system, it really should honor the existing customer
base & PS1/2/3 game enthusiast/collector by allowing the system
to run all of these games. Otherwise, it seems the only 'platform'
out there anyone should be running is a PC. I can still play all
the old PC games from 20 years ago on my system. Why wouldn't
they want this to be true on their console? Otherwise they would
need to put all of these old games in a digital library for download
purchase & there are probably serious issues to doing that (money
& time being the primary issues).

If they introduce the first PS4 models with full BC & then remove
it in later models, as they did with the PS3, that should probably
be sufficient for enthusiast/collectors.

We have several PS3 in our home. They are backwards compatible. I would never replace then with a PS4 if it would not be backwards compatible.

The problem at the moment is everyone on the internet - every tech head - is fighting over what can't be done and what could be done; then going even further and arguing over who knows what and what others don't know and why they should listen to reason that gaming visuals have reached a limit.

These people, unfortunately, are stupid.

There is a very basic perspective to take; current generation consoles achieve 250 Gigaflops or 0.25 Teraflops, and it stands to reason that everyone can understand that achieving the break from Gigaflops to a single Teraflop is a nice thing to mention -

Nintendo is aiming for 1.0 Teraflop of system capability. It's virtually guaranteed at this point in time.

It is highly likely that Microsoft are aiming for 1.5 Teraflops of total system capability but... there are signs that there is some form of heavyweight Xbox Next that has 2 Teraflops. At this point in time, it's very hard to tell, but there are signs of this happening.
Why? Because of Epic's Unreal Engine 4. Because of Crytek's Cryengine 3.

Sony is highly likely aiming for 2 Teraflops.

The only single inhibitor that these game console manufacturers ("makers", rather) have is that they have to abide to "green policies".

The TDP standard they're aiming for is between 100 and 200 watts.
That's the only wall that stands in front of these next Next Generation consoles.

Is 1 Teraflops achievable per 100watts?

Not on x86 architecture it isn't.

But PC x86 tech heads - the knuckleheads of the industry - defy reason by claiming you can't quantify 6x Xbox360 with the Xbox720's custom 6670 GPU - or its intended architecture.

Well you can. It's simple. It's 6x 0.25 Teraflops which equals 1.5 Teraflops.
This is what Microsoft are aiming for. 1.5 Teraflops at less than 200watts.

95% of the game forums with their "resistant" registered users on the internet are the biggest numbskulls this decade has ever seen.

Sony has every chance in 2014 to achieve 1 Teraflop per 100 watts with their Cell CPU and a little help from nVidia/ARM (or AMD, who knows).
But not in 2012 or the start of 2013.

Microsoft on the other hand, they can do anything. If they think this heavyweight Xbox Next needs $2Billion in R&D behind it, they're going to do that if Epic and Crytek can prove that they can shift the games industry into a whole new gear.
And Kinect 2.0 without that "new gear" is like Nintendo without Shigeru Miyamoto.

i have a ps2 and ps3 and most of my favorite games are on ps2 i hope you ps2 and ps3 games work on ps4

Sony needs to slow down and try to send qustioners out to all ps registered users before they make the final ps4.
Find out what they want in the new ps4.
Find what price they can or are willing to pay.
Considering today's economy buying a new playstation 4 is not on the top of the average family priority.
Make a bold statement to the consumer and sell the new ps4 at an unusual low price and a unpresented leadership move to sell to the less fortunate consumers and make it affordable for them also.
But in short my ps3 just crashed on me and I am in the market for a new game machine, but I'm not totally committed to Sony. If they don't make the price competive with the Xbox and other competitors, I will give considerable thought on purchasing other than the ps4. I can all ways sell and trade my games I purchased and purchase other options presented to me.

Full backwards compatability (PlayStation3, PlayStation2, PlayStation) is a must! PlayStation's best games are Grand Theft Auto and Metal Gear Solid! PlayStation2's best games are Grand Theft Auto III, Grand Theft Auto: Vice City, Manhunt, Red Dead Revolver, Grand Theft Auto: San Andreas, and Bully! PlayStationPortable's best games are Grand Theft Auto: Liberty City Stories and Grand Theft Auto: Vice City Stories! PlayStation3's best game's Grand Theft Auto IV! Grand Theft Auto V may just be added to that list! Please make sure you keep the backwords compatibility this time! I just got my PlayStation3 long after you guy abolished backwards compatability and I like a lot of other gamers won't be able to upgrade for another few years! Slow down! You're going too fast, Sony!

I still prize my ffix disks and some of the older PS1 games as well as the PS2 games. If PS does not make PS4 backwards compatible, I don't know if I will buy it at all...

Please make the ps4 fully backwards compatible, some ps2 and ps1 games are classics that deserve to be played, especially tt superbikes real road racing on ps2!!!!!

Only the early ps3 80gb's had "emulator software", the 20gb, and 60gb models both have ps2 Emotion Engine chips set into the motherboard. The 80gb systems only played a small portion of ps2 games, while the 60 and 20gb models both ran about 97% of all ps2 games. Personally i LOVE the 60gb system, and i own 2 of them. They were the only "true" ps3's made in my opinion, and i hated the fact they discontinued them simply to sell more ps2 systems. If Sony would make the PS4 fully b/c, with all 3 previous systems.. they would sell a TON of them. hell i myself would buy more than one, probably 3 or more to have in different locations. The loss of ps3 b/c with ps2 games was devastating to me. i hate getting up to swap memory cards, hate controllers with cords, and really hate having my ps2 burn out, and trying to find another one that still performs like it's supposed to. the slim ps2's are crap, and the original models are harder to find with all functions still working. Sony would dominate if they brought back B/C.

They can't forget about the PS2! I still have a lot of really fun ps2 games, like the star wars battlefront and battlefront 2, as well as many others. Please include compatibility for ps2.

I own the the MGS4 Playstation 3. It was the last of the great big consoles with backwards compatibility built in. I still play many of my PS2 games on it and don't have the graphic differences that my friends with PS3 Slims do when they play the same games as I do.

I am wholeheartedly sided with it, things should look better on the newest hardware rather than they did on the old one.

In PCs, for example, they introduced Morphological Anti-Aliasing which make older games look far better on the newest graphic cards.

The problem with Sony is that we forget it still manufactures the PS2 in large quantities and it's far more profitable to sell a whole system than offering a software emulating it.

People buy the PS3 mainly because they are interested on PS3 games, nobody buys it for just PS2 ones.

For Sony is more advantage to keep the PS2 the better option for playing mainly PS2 games.

We mustn't forget the all important PS2 games either, like Jak and Daxter and Kingdom Hearts
