As in, with a similiar 'realistic' art style and Ocarina of Time like direction? Or would you rather have a new type of Zelda game like Skyward Sword or Link Between Worlds?
Twilight Princess is my favourite Zelda to date, and I think that its visual style would be really good at showcasing the Wii U's capabilities. Sure we have Wind Waker HD, but that's just a remake of a gamecube game not to mention it has a different style. I am very interested to see how a Zelda with Twilight Princess' art style would turn out, especially after that tech demo back when the Wii U was first announced.
Wasn't the scenes shown with the Wii U hardware at E3 last year a pretty clear indication that they are working on this exact kind of thing already? Assuming that hardware demo was not made specifically to be that and then completely abandoned.
