GOW is probably pretty efficent on the PC then, and not as optimized on the 360. one thing about computers though is there more customizable, a good example of this is drivers. software controls the hardware, instead of firmware as in the 360.
i think they should make drivers for consoles, to better improve there performance as newer games come out. cant wait to see the PS3 used to its full potential in a couple of years. although i think they over did themselves with, it has TOO much power, by the time the next Xbox comes out the PS3 will be "in its prime" but the new xbox will be newer there fore "better" in most viewers minds, and probably to most high knowledge users as technology changes so fast.
i think microsoft made a good decision with the 360. get it out sooner and make lots of people buy it, buy exclusive game rights. and when the 360 game sales drop release the games on PC. then when the 360 wears down make another system.
gamers have the money to buy new consoles, just they only come out with them every so often. i say making more systems over time will make more money.
