Sony:

I'm mostly interested in seeing more of Playstation All Stars Battle Royale. Also announcements of Vita titles from other Sony and other developers, Infamous 3, and the new Quantic Dream game.

Nintendo:

3DS games that I'm actually interested in.

Microsoft:

Not interested in Kinect or Halo 4, so there show will probably consist of third party titles that I probably won't care about. I guarantee that Microsoft's showing will have Black Ops 2, like it's had Call of Duty and other FPS titles every year prior.

Other:

I want to see Grand Theft Auto 5 gameplay. What they did to the Rage engine. If it's only slightly better than GTA4 that's fine witih me. I'm just hoping it's much more fluid than previously.
