It was easier for them to make the game on xbox and port it to PS3... If that's no longer an issue for next gen systems then what sir?
And please show me a game that looks just as good as GOW, KZ, Uncharted, and Heavy Rain on Xbox...
If that's no longer an issue for next generation, then Sony did a better job at engineering their system this time around. I'm no fanboy I appreciate what Sony brung to the table this generation and I look forward to what they have in store next generation.
Gears of war and Forza look just as good as those games you mentioned
