yeah saying that an unreleased game with no footage whatsoever will have better graphics than what we got today is ludicrous. you guys mentioning uncharted 2 and god of war 3 are just being insane fanboys.
anyway, the undisputed winner of graphics will always be gran turismo. and it does have footage, if prologue is anything to judge it by (and of course it can only get better)
1. GT5 (Prologue or whatever)
2. Uncharted: Drake's Fortune
3. Metal Gear Solid 4
kingpins of graphics, strangely all ps3 exclusives (perhaps some more tapped potential there, with more time and effort dedicated to ps3). i don't really agree about killzone 2 because it just seems to be just a lot of gray and black.
