Last year rumours swirled of a Pokémon fighting game for Wii U, as trademarks for Pokkén Fighters and Pokkén Tournament arrived in North America shortly after the following video from the Tokyo Game Show had grabbed attention. At the end of the video there's a glimpse of Mega Lucario and Mega Blaziken facing off in what could conceivably be Wii U-level visuals.
It's been a little while since that burst of activity, but in timing sure to have fans eagerly looking ahead to a certain LA event, patent records filed in Europe on 1st May match those from North America.
As before this could be something of nothing, or may be non-game content such as films or an animated series. With E3 2014 on the horizon and an apparent effort to bring all major regions into line, we shouldn't have long to wait before we find out.
