My predictions:
-Plants Vs. Zombies 2 will capture the attention of 4 year olds everywhere, becoming the next Kinect or Angry Birds.
-Xbox One will try to show more gaming features, will be outclassed by PS4 and possibly Steambox.
-Nintendo will reveal a "surprise" niche to try to save the Wii U.
-Handheld games will be saturated by Soul Sacrifice and MH3U clones.
-Every FPS game will look the same and include the same "new mechanics".
-The Super Smash Bros. demo will be terrible, causing Nintendo fans to boo Reggie Fils-Aime off stage.
-All of the racing games will be identical due to diminishing returns on graphic power.
