I think the big hitters this year are going to be
Codename Kingdoms : After seeing what Crytek did with Crysis 2 doing multiplatform development and there debut game on consoles, I'm waaaay excited to see what they can do with this game. Graphically it should be incredible.
Gears of War 3: Nothing needs to be said. This game will be Epic and Incredible.
Forza 4: For me personally will probably be the best racing game of this generation. GT5 is superior in physics and realism but Forza offers more customization and the actual racing mechanics just feel better.
Strong Kinect lineup: Pretty much every single major developer is working on some form of Kinect game right now and title like Project Draco, Star Wars Kinect, and Steel Battalion are just the tips of the iceburg.
I also expect an anouncement for Shadow Complex 2, and 1 or 2 large scale 3rd party exclusive announcements.
