If you are talking about Tri force Heroes, then it would probably be a game like Phantom Hourglass or Spirit Tracks with their Top Perspective point of view. It may not even use the circle pad, only the stylus.
Zelda Wii U may be like the first Zelda game, with no map and nothing to indicate where you are supposed to go, maybe revisiting the roots. It may encourage you to explore alot, which I think sounds like a great idea, if you like to get lost.
