Im sure you'll receive a lot of hate for this but I agree with you TC.
I don't think he'll get hate for it. While I don't think it will be a new Pokémon, I wouldn't be upset if it were. I said in another topic that I'm 95% sure it's a Mewtwo form, 5% sure it's a separate Pokémon. That's not because I necessarily want that, it's just what I think will happen.

With the addition of psystrike, I just don't believe Mewtwo drastically needs a new form change. Mewtwo is still an extremely strong contender in the metagame. Deoxys already has 3 drastically different form changes for unique stat distributions.
In all honesty, I don't think anybody has wanted a new Mewtwo form change rather than Mewthree. It just seems like an odd choice.
