Jeez Bebop you spout some crap, Mr Jinx's point abuot blu ray is completely valid . If you knew anything about game development, the higher resolution the texture the more space it takes up, it's as simple as that. Almost as simple as your one sided fan boy posts infact. And who you callin newb, since when did 18 posts qualify you as a forum expert?
The ps3 has just come out, nothing is really taking advantage of the power, and don't use the Gears of war on 360 blah blah blah, the Unreal 3 engine can run on even current high end pcs, it has to do with how it meshes the higher res models, but i'm not going to give you a lesson in graphic engines.
Take a chill pill and go enjoy your 360, your constant ps3 bashing is not constructive.
