At one point, it was listed for Wii U, but the platform was removed from the list. My preorder poster says 2013, but Bungie isn't getting it finished 'till 2014. They're already running over Activision's expected timeframe. They don't have much time available to port to more platforms, and unfortunately Wii U has the least sales of all the consoles on the market. If they're going to make a fifth version of the game, it's going to be PC, and even that isn't looking promising.
