These days the same companies behind computer graphics are also behind the systems graphics even. It is intentional too, as Sony has stated both with the PS2 & PS3 it is a PC replacement.
I know, it's terrible.
I love the way how consoles were simple machines, no problems playing games, no problems with the consoles themselves...
The more consoles will be PC's, the more problems will appear. (Updates, virusses, hardware failure, ....)
Mark my words, next generation Microsoft will announce the Xbox 720 (or whatever they'll call it) with Vista on it...
"Now your console has all the functionalities of a PC, it's a revolution!!!!"
Seriously, the day that comes, I'm no longer buying consoles.
