This image has appeared in several japanese forums and shows what appears to be a new Mewtwo form, and this may be related to the fact that the japanese magazine CoroCoro promised news on the news about pokemon on the next issue, and the fact that news about the next-generation may be shown saturday on the Pokemon Smash TV Show.
Update: Another image
