I don't keep track of MS or Sony.

For Nintendo, I'm slowly starting to give up hope on Pikmin 3 and some other semi-announced games (Kid Icarus?).

For Nintendo, the presentation will probably be:

15 minutes of how succesful Wii and DS have been. (They show some good new games like SMG2, MH3, Sin and Punishment...)
15-20 minutes of 3DS.
20 minutes of new games for Wii and DS.
5 minutes of Zelda.
