Wii U Version

Does anybody know if the Wii U version will be different? Like maybe off-screen gameplay on the gamepad? I have a feeling they are going to use the gamepad as a map.. I hope they don't use the nunchuck. I hate that thing, it's too small.

First thing : It won't use the NFC in the gamepad. Quite logic but still.
Second the developers are watching at things like : Off-tv play, Touchscreen buil, Splitscreen off-tv multi player and that kind of things. Nintendo also announched the function of sharing content through Miiverse so maybe we will hear more about that to.

Currently, we don't know. Skylanders proves it's possible to have the game running at a solid framerate with RFID info getting streamed in, but depending on what can be achieved with all types of discs etc. being on at the same time, It'd be reasonable for them to scrap it if it just doesn't work well.
