Ubisoft has a finished Wii U game that it won't release until the console sells more

Maybe it's another Rayman game! That game got delayed for the Wii U for other consoles because of its poor sales. It could happen again!

In a more serious note, if they ever decide to port it to other devices and cancel it for the Wii U, I hope they let us know what the game is.
