An official fighting controller will be released for Pokkén Tournament when it launches at spring for Wii U. So far, the controller is only announced for Japan, but hopefully it will be released over here as well since Pokémon usually means big business.
As it is a fighting controller, it is of course wired and doesn't come with any of the usual fluff like analog sticks. This is bare bone control pad with a directional pad, four action buttons and with triggers ZL and ZR moved to the front as standard buttons.
Below is the first picture of the new controller.
