That's what we get for thinking that we're actual gamers. We should remember that we Nintendo fans are blessed for every single sainted third party game that even graces our unworthy devices, and we were foolhardy to deprive the consumers of the hallowed PS3 and 360 for any game, let alone a Rayman game.

well to be fair, it was the PS360 gamers who bought the most copies of the last game, so if anything it was foolhardy for Ubi to have it exclusive to Wii U in the first place.
