In addition to all the repeats above,
1. An unexpected TBS game for Wii U.
2. New hardware add on for Wii U that includes a breakthrough in some regard to "healthy" software.
3. A push for the new 3DS to be used in conjunction with the Wii U. Probably to stream the n3ds to the TV through wii U and/or use the n3ds as a gamepad on wii u games
4. More crossovers, probably linked to point one above. If hyrule warriors or pokken was talked about prior to their announcement they would also have sounded insane and Hyrule warriors has been a success to date.
5. Going out on a limb but Nintendo will probably open the Wii U to be used as a streaming device for steam machines to use as an extension to the living room TV through an app. It has the capacity but valve have postponed all of those possibilities. People who own wii u and pc have a nice combo.
6. Princess peach stand alone game
7. Bowser standalone game in the vain of treasure trecker but has the feel of crash bandicoot.
8. Wireless GameCube controller which would explain the lack of adapters.
9. Facebook integration on Wii U or at least an app.
