It's Pokken for arcade, which has a huge scene in Japan, and still doesn't technically have a Wii U launch at all.
Besides, spinoffs don't count towards "Pokemon doesn't sell well on X" or anything like that, since spinoffs have never sold as well as the main games. Why would you bring that up and not Pokemon Rumble U, which is already out?
