The motion controls in The Wind Waker HD (Aiming) were absolutely fine. I would even go as far as to say that they enhanced the game (for me at least).
I don't think that forced motion controls of some sort (even if bad) would make me reconsider if i buy the game.
And even if they were bad, i'm pretty sure that you could just use the sticks instead. The new Zelda doesn't seem like a game that's built around motion controls (like Star Fox Zero) but rather a game that, like WWHD, uses motion controls to enhance the gameplay.
