During the recent Pokémon Game Show in Tokyo, a short video concluded with an image that sparked rumours of an upcoming Wii U game, as Mega Lucario and Mega Blaziken were shown facing off in what certainly looked like a sharp 3D graphical engine not beyond the realms of the Wii U.

While The Pokémon Company has said nothing, Siliconera has dug up video game trademarks for Pokkén Fighters and Pokkén Tournament, both registered in the U.S. by The Pokemon Company International on 15th August this year, just ahead of the game show in Japan. That's it as far as the rumour goes; trademarks have certainly pointed the way to plenty of games in the past, though on other occasions have led nowhere.

We're unsure of how this branding would fit, but check out the video again below (the tease is right at the end) and let us know what you think.
