Yay. They've already announced a "hypothetical" 3DS Zelda that would be original (i.e. not a remake). So I think it'll be for the 3DS.
I'm sure if they made one for the 3DS, it would probably stick to the classic Top Down view Phantom Hourglass and Spirit tracks had. Plus, I wouldn't doubt them bringing Toon Link to the 3DS as well. On top of that, there's the rumored Majora's Mask re-make. For the Wii U, I'd like to see that HD Twilight Princess-styled Zelda game. The demo they had at the last E3 looked amazing and I wouldn't doubt that it's probably the style they're going for. Maybe sometime late in the lifespan of the Wii U, they could make an HD remake of Skyward Sword or even Windwaker. That'd be pretty nice ^^
A Majora Mask remake would be dumb and a waste of time. I'm pretty tired of all those remakes, just buy the original. We want new games.
I agree about the Majora's Mask remake. If anything, they should've included it in with Ocarina of Time 3D instead of keeping the whole Master Quest thing. Then again, the remake of it was just a rumor after all. I do enjoy the remakes though. So long as they're developing newer games at the same time. Originals can be hard to come by and it's always nice to play your favorite games a second time remastered.
