If the new Zelda game lives up to expectation and customer review, and the sword control is less problematic than with Skyward Sword, the sword moves likes you want it to if your 'in the moment' and not stopping to surgically position the remote!! I would buy it quite happily.
And although i haven't used a touch pad control outside of the DS i can imagine that with both the pin point precision and motion control you get with the wii remote (use to love chain and ball in Twilight Princess and aiming the bow with the remote) and quick access to menus, sliding block door puzzles, maps and everything else that the touch screen can be used for, i think that you could make quite a game with a real technical edge.
I think that OOT and TP are still class games, with what the newer consoles can handle in terms of expanded maps, better environmental interactions, weather systems etc and some harking back to what made OOT and TP so fun, combined with some refined control systems the next generation of Zelda games could be more epic and fun than ever and retake/hold their rightful place in gaming history.
PS: Imagine the Zelda games from the Snes and beyond revamped with new graphics and technology, but with the same plot, gadgets, gameplay style etc.... Epic
