New Form of New Pokémon ?

Really can't say but a new Pokemon is what i think! Maybe it's a clone of Mewtwo, Mewthree? I would definitely want it to be Mewthree though. An Evolution is unlikely and a new forme? Can't really say.
P.S The design sucks!

Unless it involves those DNA splicers in B2/W2, I'm voting for a new Pokemon. It looks smaller and meer stable compared to Mewtwo, who just looks like he's on steroids (don't get me wrong, I like Mewtwo).
Perhaps it's a clone that's stronger but calmer and easier for humans to control.
Since the new games appear to focus on genetics, I can't wait to hear its story.

theres a new movie on dvd involving a shiny genesect and mewtwo called the extremespeed genesect the awaking of mewtwo

It's definitely in the Mew "series," if that's an appropriate term. I can't decide if I like it of not. I mean, he's kinda cute. He could be Mewtwo's younger brother. :3

Well, if Mewtwo didn't evolve from Mew, I'm going with Mewthree.

I tried cheating door looking it up on the official Japanese Pokemon site, but they're keeping it vague until October.

All i can say is that It Is related to Mewtwo, that much is a fact
the rest is still a mystery until further notice

Apparently its an 'awakened' form of Mewtwo according to what serebii got off the posters ¬¬
