Has there been another video since yesterday? I was on a imageboard (and I would like to have it known that it was NOT any of those garbage 4chan boards) and discovered Talonflame. I also saw what seemed to be a screenshot of a Chespin battling multiple Axew at once.
Just go and check any major sites like serebii or pokebeach. There was the pokemon roundtable last night which revealed new info like horde battles and sky battles as well as a few new pokemon. And corocoro magazine was leaked this morning with new pokemon and characters.
