I am SO HYPED UP for Skyward Sword!!! Cannot wait for November; I've been stalking the Internet for news of it practically every day, and once I get my hands on it... TAKE MY MONEY NINTENDO-!
Yes, Zelda has a formulaic approach, but that formula definitely works, and hasn't disappointed in all of 25 years. In SS, it looks like there's some new concepts and refinements (in terms of MotionPlus, although we've yet to see if it fully works), the graphics look terrific (to all haters, two words: "Wind Waker"), and also orchestrated music...
Skyward Sword could well be the best Zelda ever! In my opinion, there's even a slight, slight chance that it could surpass OoT, at least in terms of gameplay, from what I've seen. Although OoT has a special (nostalgic) place in people's hearts, so it would be very unlikely, and quite a feat if it does. Still... one can hope.
