It's actually a Gamecube game that at the last minute was turned into a Wii game. It was in development for Gamecube originally but since the system did poorly and the Wii was released prematurely, Nintendo decided to port it to Wii. It was released on the GC later as originally intended (I'm guessing) due to pressure from people who bought GC on the promise of the new Zelda game.
