I think i'll start off by talking about something everyone has probably heard about. The New Zelda. Now, I'm a little worried. It looks too much like the previous Zelda. Twilight Princess was great but do we really need another. The Zelda franchise has been known to be a fairly innovative franchise and this has some interesting concepts but will it be different enough. Wind Waker featured the sea which had to be navigated and Twilight Princess has the wolf and these 2 ideas really changed the way the game was played but I don't think building a game around the idea of cutting in a certain way will be innovative enough.  
Now, I have no doubt the temples which will inevitably be in the game will be great but will that be enough. I'm sure the hardcore will lap it up but will newcomers or casual Zelda players want to pick up a game very similar to the game they picked up 4 years ago. The New Zelda just makes me a little uncomfortable. I want it to be good but not just to me.   

I'm of the opinion that a game doesn't need to have a gimmick to be great.

Yes, but I've always thought that Zelda games were innovators. The new Zelda just feels like a gimmick. Its not the revolutionary new concept I was hoping for. Ocarina of time introduced us to the lock on system and this doesn't seem to have anything close to that
