I don't have many complaints about the motion controls from Skyward Sword like some people do, I thought they worked pretty well and allowed for a really cool and fresh take on enemy design. That said, for me personally, having full camera control is absolutely vital for an optimal experience and in no way worth sacrificing.
In a series like Zelda, where you're constantly required to survey your surroundings (even more so in an open-world Zelda, I'd imagine), being restricted to one field of view at any given time (as you are in most 3D Zeldas) can be a pretty big handicap. Sure, you can change that field of view, but to do so you have to deliberately reposition yourself and abruptly shift focus. This disrupts the pacing of the game, and it's very possible for information to be passed over during the transition. Moreover, you're now stuck with that field of view until you reposition yourself again and shift focus again. Going into a first-person view does offer more freedom with the camera and allows you to get a more complete understanding of your environment, but it forces you to literally stop in your tracks to look around and shifts your attention away from whatever you were doing before or could be doing simultaneously. Skyward Sword did let you move around in first-person view, but your abilities are still limited to just looking around, therefore there's still a shift in focus. You have to go from traversing a dungeon/overworld to 'Looking Around'. Being able to move while 'Looking Around' doesn't really do much besides give the illusion of better pacing.
Full camera control enables you to always have complete understanding of your environment (which, again, is super important in Zelda) while simultaneously being able to actually traverse the world and do stuff. I have no problems with motion controls in general, but because I can't see both motion controls and full camera control being possible at the same time, I do not want motion controls to return.
That was my opinion on the matter, though. What I think they'll actually do, I'm not sure of. The character in the teaser trailer, whom Aonuma confirmed to be Link, pulled his bow with his right hand. I checked footage of every single 3D Zelda, and he only does that in the games where he is right-handed, which are the games that use motion controls. This seems to imply motion controls will return. However, that one detail isn't really enough to base a prediction on, so all I can say is I don't know if the game will utilize motion controls or not.
