Aye. The whole point to sequels, in my eyes, is visiting new places and what have you. Sure, it's nice to visit places you've been to before in previous games, but only so much. Kingdom Hearts II, for example, over did it with its revists in my mind. We didn't need to go to Atlantica again, for instance(though the minigames were neat.)
As such, I am firmly against visiting Zeal or any other location previously seen that would not have major importance to the story. Now, if we pull a Back to the Future and see a scene from the original or Cross from a different perspective, that's another thing entirely.
