There was an interview somewhere in which Anouma said that the team will stick with Skyward Sword's style, because it's the perfect balance between toon and realistic (their words) for everyone.
That was some time ago. A quick Google reveals:
"Zelda producer Eiji Anouma has revealed that the next instalment of the acclaimed Legend of Zelda franchise for Wii U will feature an art style that hasn’t been seen before in a Zelda title. Anouma says that the art style will be neither ultra realistic, nor cartoony, but it will be something entirely new that has not seen in a Zelda game before. Anouma also revealed that the next Zelda title may feature downloadable content, but the content would have to be “worth it for the user.” Here’s what he had to say about the art style for the next Zelda.
“The thing about Zelda is we want everything to be unique, whether it’s the graphical presentation or the gameplay.”
“It has to be something you can’t see anywhere else. We wouldn’t want it to be ultra-realistic because you can see that elsewhere. But I can’t say that it’s going to be cartoony-realistic like you mentioned, the fantastic presentation that we’ve already done in the past. It will be something new.”
So there you have it folks. They're going for somewhere inbetween the two (again) but not quite like SS.
