Your eyes are not deceiving you: those are new Pokemon
A dedicated hacker by the name of Smealum has uncovered these babies. In counterclockwise order the new Pokemon are: Volcanian, Diancie and Hoopa.
Serebii claims there aren’t confirmed, but Serebii posted (and the subsequently took down) three new Pokemon last week. I think these are all too real. I thought there wasn’t going to be DLC? Doesn’t this count as DLC?
Also revealed: Mega Latias and Mega Latios. They look a tad similar. [❤]
