It's easy, everyone not owning a Wii U that wants to play the game just has to buy a Wii U!
Same as people who want to play PC games buy a PC, people who wnat to play PS4 games buy a PS4... Why suddenly Nintendo wouldn't be "allowed" to keep the game they make on their hardware???
When things come to Nintendo, people who don't play on Nintendo systems seem to lose the grasp of reality...
