So let's assume with the Wii U that we do get a new, wireless Wii-mote and Nunchuck-style controller with motion plus integrated into both parts of it. The Wii U tablet could just sit next to the player as a map/inventory screen that you simply touch to pause the game on the TV and then after picking up the Wii U tablet controller for whatever means and finishing, just switch it back to map mode or whatever and place it back down.
That's a cool concept and I wouldn't mind seeing it if done right, but I think the Wii U should just have a classic HD Zelda only your inventory, map, health, mana etc is all on the controller. I also would like to see the aiming style from OoT 3DS implemented because I found it unique, gripping and addictive.
