The facts are:
1. That most game reviewers and the loons at LOT have no credibility when it comes to judging graphics on a technical level. They are in no position to delcare anything official. Accept their findings at your own peril.
2. The X360 hasn't had devs really pushing it. A lot of it's big players have been Unreal engine games. Finally someone has come along and gotten something great out of it. For years the PS3 has had Naughty Dog and Guerilla kicking the PS3's ass with great results.
3. The X360 has a better GPU than the PS3
4. KZ3 also supports split screen play, which Crysis 2 doesn't. This is a big engine consideration.
5. KZ3 runs better.
My opinions:
1. KZ3 even looks better than Crysis 2 on extreme settings for PC (which is what I played it on).
2. Crysis 2 is a turd of a game with a horrendous story.
3. KZ2 > KZ3
4. Crysis 2 looks works than Crysis 1 (could almost put this under my facts list, but someone might argue otherwise).
5. When Uncharted 3 is out, everyone will be saying the same stuff about the PS3 making the X360 looking silly, quickly (and foolishly) forgetting about any of this debate.
