I thought Skyward Sword was the most emotionally engaging Zelda story yet; but I wouldn't want to see a repeat of that style of game. While I think both Retro and Monolith Soft would do a great job, I think the kind of direction From Software have would work brilliantly. That doesn't mean they should develop the game, though. Aonuma has already said that looking at the two basic conventions of Zelda--single player and sequential dungeons--is the starting point for the next Zelda, implying a return to the conventions of the first game. Married with Miiverse, you'd have a very Dark Souls-esque Zelda, which was itself heavily influenced by the original Zelda. I really think that's the direction to go in.
I'd love to see them rethink the combat mechanics, too.
