In short from gamepro :

The 4 best things about MGS4

The graphics: You thought Gears of War looked amazing? Think again. Metal Gear Solid 4 will blow you away with its ultra-detailed characters and intricate environments, painting some of the most gorgeous graphics seen this side of Crysis. In motion, the graphics look so realistic that your eyes begin to register the visuals as a movie rather than a game. From what we saw, MGS4 puts its 50GB Blu-ray disc to outstanding use.

The guns: The final game will feature over 70 weapons, from lethal assault rifles to silent tranquilizer guns, and you can outfit many of them with scopes, recoil grips, laser sights, flashlights, and more. Collecting enemy weapons will unlock new guns and "Drebin Points" for further customization.

The sound: MGS4 has some of the crispest, clearest sound effects we've ever heard -- the booming gunshots will make your hair stand on end! The Hollywood-****soundtrack is also predictably fantastic, and Snake's raspy voice sounds more desiccated than ever. GamePro editor Sid Shuman went so far as to say that MGS4 has "the best sound I've ever heard in a game."

The story: MGS4 is the darkest Metal Gear game by far: Snake is in terrible physical shape, and the world seems to rest on the brink of self-inflicted annihilation. Though the mood is dark, it's not depressing: you'll find plenty of characters to care about in this war-torn world.

Haze has a lot to prove until it becomes a "big name"...

if you're asking about promising games, then i would say Haze.

From 360, i would just be interested in Fable 2 and Alan wake.
