I always had the impression they would come back and do a Wii version myself. Interesting that they actually somewhat confirmed it...well confirmed they're interested.
There is definitely a lot of potential with the Wii but they are going to have to develop a version specifically for the Wii, maybe not redoing everything but adding a new feature set around the Wii is the bare minimum imo.
Either way I am still not going to be interested in the game but I will be amused by the folks who weren't interested before that all of a sudden become interested now that its on their console lol.
