Because those are last gen systems. Should Nintendo fans not complain at all then and accept this? I don't think so.
what kind of logic is that? the game was announced as PC PS360 and Wii U and was funded by users of thsoe systems. Whether they are last gen or not is irrelevant as they still funded the project. Not even sure why you brought that up.
My point is Wii U owners are still getting the game, so lets not act that they got screwed over, yes it sucks they have to wait but thats what it is. PS360 owners got a rawer deal and they arent complaining
