PS3 was a lot more expensive to make than it would be now. TBH a higher specced machine with newer parts would cost much less than PS3 cost to make back in 2005/2006. A more powerful CPU than the cell like an FX series Quad core could be bought by Sony for about £40, a GPU based on something like the HD 7870 would probably cost them less than £100. Bluray was an expensive, new piece of tech when PS3 came out, it's dirt cheap now and would probably only cost Sony about £20 to put a 12x BD Rom in PS4. All in it would cost Sony about £350 to manufacture and package a PS4 with the above spec, 2GB of VRAM and another 4GB of standard but fast DDR3 for system RAM would likely be major overkill in a console, but Sony could use GDDR5 as the RAM for everything, either that or DDR4, 2GB would probably be plenty of RAM, but 4GB to future proof the system more and we'd all be gaming at 1080p+ resolutions, with 60FPS and high to ultra levels of effects compared to PC in games, even in complex and highly detailed environments. Being that consoles are closed systems developers can use more of the system's power for the performance of games next to what a similarly specced gaming PC could achieve. Overall we'd be looking at a console with more than 12 times the power of PS3, just look at what Naughty Dog could do in a game like The Last Of Us or Quantic Dreams Kara Tech Demo, then imagine what they would be capable of with even more power and ram, we'd be seeing the graphical sealing reached at 1080p, so Avatar levels of graphics are quite possible. Something like a poorly optimized Crysis, with all of the best textures and graphical effects even the most modded versions of that game can have would be easily doable on this hardware, especially when a game is made for such a system, this system would likely have more than enough power for games like that. PS4 manufactured at that price, will likely make a loss for Sony at release (but likely not as much as PS3 did), just like PS3 did, so a release price of about £300 is likely or just under $500, maybe close to $450 with the cost of parts in different countries. Even if PS4 was a higher specced machine it will likely not go above £400/$650 for the release cost to consumers. BTW PS4 isn't coming out this year, if it was then it would've been shown at this year's E3, if PS4 was ready then it would easily take the wind out of Wii U's release, but nothing's been shown yet, so 2013-2014 is likely the release time.

yah, most certainly

you think?

If you make a console upgradeable, you effectively extend the life of the console. If the console has too long of a life then people will not buy the PS5, PS6, PS7 and so on and therefore this will mean less money for Sony. However, I think your idea would actually work very well and be awesome IF... Sony was the only place that you could buy the upgradeable parts from. This way Sony still gets their money and the consumer gets more options. But if Sony is trying to compete with a whole crap load of other companies when it comes to buying parts then I think they will lose money in the long run because of competition.

Punctuation? I bet no one ever reads anything you type. I certainly couldn't be bothered...

then don't, why would you think that any of us care..?

EB games in Australia have been advertising pre-orders for ps4 for wait for it....... $899Aus which I think was about what the ps3 sold for when it was first released in Australia. That will make it the $599 no one was happy about last time. Very disappointing Sony. Check out the EB games Aussie web site and have a look for yourself. ebgames.com.au

You basically said to make it more expensive, Learn to spell please for the benefit of everyone.

The ps2 Socom games, ALL of them, ruled...period.
