PS4 should not be so powerful next gen?

[GodofWine]

I think due to the (quickly) rising cost of developing games that use the full power of either HD console already, that we will only see a small bump in total performance (RAM / processing speed) with very little change to general architecture or programming needs in the next gen.

20-70 million or more to develop a 'blockbuster'game that might sell well, or bomb for either console is quite a daunting investment for a dev. to make.

And lets face it, games like Gears / KZ2 / Heavy Rain (speculation) / etc look fantastic, not too much further to push non-CGI graphics.
