You see that up there? That rather blurry screenshot is from a retrospective trailer for Pokemon X and Y at the just concluded Pokemon Game Show in Japan, a three day long expo for all things Pokemon.
The teaser in question showed off the evolution of the Pokemon series from Red and Blue all the way to X and Y on the 3DS, before announcing the release date for those games; it then proceeded to tease everybody with that mysterious image that you see above.
What might it be? Your guess is as good as anyone’s. It looks like a Wii U Pokemon game, but if it is that, what kind of a Pokemon game is it? Something like a Pokemon Stadium or a full fledged RPG would actually help the Wii U; something like Pokemon Rumble or Battle Revolution would be useless.
We don’t know anything more about the game yet. We don’t even know if it is a game. But we’ll keep you posted on it.
