dude haze is also coming to the 360, then we will see the big difference. (which won't be there). And it doesn't nearly look as good as crysis.
It hasnt been confirmed for 360 yet. It was annouced,and ubisoft hasnt said a word about the 360/pc version after they dropped the release dates. Do you think gears of war looks nearly as good as haze? and according to some of the developers of gears say they had to put the 360 to its maximum to achieve those type of graphics.
