PS4 is using x86 architecture so backwards compatibility would cost even more $$$ because of the Cell processor in the PS3. Either programmers re-code PS3 titles (Exclusives) or Sony includes the Cell which they of course would not do (Sony has been bleeding money but fortunately they have plenty of assets to sell off).

The PS4 and Nextbox is the PC gamers dream come true. Both consoles are "PC based" and developer friendly. This will usher in the era of better optimization. Its a win-win for both the console player and PC gamer.

I get that its hard to do with the technology, but I was always impressed with the PS2s ability to play games for the PS1.
I do like that they’re now offering PS1 games from the Play Station Store, but they need to expand the library, and there are a lot of PS2 games I’d like them to make available for download with the new console. It makes sense, having PS1 games become available for the PS3, and then have PS2 games become available for the PS4. There are some especially rare games I no longer have and would want to be able to play again.
