Eiji Aonuma announced today that the game has been in development since 2011, and that they will be making some changes (and possibly additions?) to the game...
However, this game was the last 3D Zelda game I really felt satisfied with. I love that it doesn't totally hold your hand, and that there is so much "life" to the world, where you can explore and get real rewards. If they change the time mechanic and its penalties, the game will be broken, though. The whole idea is being a detective, discovering routines, and how to best utilize them. The involved town in this game is arguably the closest to classic Zelda towns. And once you learn those routines and get certain items, you can go around certain events. It was genius. I can't believe there is so much intimidation surrounding this game. I just hope the 3DS version will be as good as the original.
