I would personally say the original GC version is way better, but I'm biased. It's the only version I played (I wanted to play the GC version, and didn't care about the added Wii features). To me, that's the "pure" way to experience the game, but whatever.
I would love if they made an HD TP remake, WWHD style, but who knows if it'll happen. It would be nice if they surprised us with that the way the did WWHD, coming out for this holiday season, but I certainly don't expect that.
