Apparently I missed the memo and this teaser image that there was a Pokémon fighting game in the works. But this morning brought us a teaser trailer and official news of Pokkén Tournament: a Tekken-style Pokémon brawler. The full video announcement showed Tsunekazu Ishihara, the CEO of The Pokémon Company, meeting with Katsuhiro Harada (The director and chief producer of the Tekken series) and Masaaki Hoshino (producer for the Soulcalibur series)- so we at least know the game is coming from good stock.
However, it seems that the only plans they have for Pokkén Tournament is for it to be an arcade-only game in Japan sometime in 2015. They haven't given any word on bringing it stateside, or even to the Wii U in Japan. I hope that they at least have the common sense to have Dokken do the Pokkén theme. I hear they're huge in Japan.
(thanks to Polygon for making me aware of this.
