I would love a new overhead, or 3d portable zelda. In fact as long as its not touch based I want it. I never finished spirit tracks, I just got too burned out on touch screen controls for the series. Kinda shames me to say that as a zelda fan, but I just ran out of steam on it.
Probably won't see it, but I would love a sprite based Zelda ala Link to the Past. In 3D with multiple layers, to me that would be just gorgeous to play through.
