There is no such thing as inovation, in the pure form of its interpretation.
Any kind of work takes up ideas from things that came before it.The same way that western RPG or action adventures games in general took out ideas from Zelda, Zelda is also taking ideas from other games.This is how the world works.The thing that you should be concerned about is if the ideas they are implementing into the game will work on its own, and if they all work out to make a different game, a game that has the Zelda feel but also has something different in it.And I guess it will be.
Personally I think this is shacking up to be the next big Zelda since Ocarina of Time.Time will tell.
