This game has zero potencial on WiiU. Not only the game is graphically inferior, but also is coming veeeeeery late AND WiiU users are not buying these kind of mature games, and Ubisoft already said it will be their last mature game on WiiU. So I don't think it will pass 200k.
WiiU is for Nintendo games. It's decided by destiny itself.
