PS4 - Playstation 4

I agree with a lot of what you say, but regarding PC versus consoles, I don't think PC gaming will ever drive away console gaming, no matter how low the cost of PC gaming becomes in relation to consoles. PC and console gaming are by and large two very different beasts. You mention consoles having to offer unparalleled experiences, well they already do that.

There are a couple of crossover genres like FPS and sports, but the variety of games available are generally vastly different. A gamer who likes fighting games, JRPG's, platforming, action, etc., will find little to play on the PC, just as gamers who like simulation games, puzzle games, RTS's, CRPG's, etc, will need to stick to PC gaming for the most part. Things still haven't changed much in that respect in the last 15-20 years, despite more and more gamers of both platforms, and easier portability of games between PC's and consoles (especially between PC's and Microsoft's consoles).

You also have to consider that consoles are the only real choice for party gaming, which has become increasingly popular as the appeal of gaming has spread (as typified by the Wii). How many multiplayer games have you played with friends in front of your PC monitor, compared to in front of your TV on a console? I imagine it's no contest. So console gaming definitely does offer things PC gaming doesn't, and perhaps never will.
