Here are a couple of quotes by Zelda Director Eiji Aonumaaken from the new issue of GamePro "I think that the Wii is a very powerful console that people can expect a lot of things from and I would like people to look at Twilight Princess as a baseline for what the Wii is capable of" and "Its certainly not a game thats maxing out the powers of that platform(Wii)"
