It's just starting now (with a Sinnoh anime episode), but I'm pretty much calling it, whether it's revealed today or not. I looked closer at the movie site, and at the end of Mewtwo's description, there's a sentence in a differnt color that essentially reads "What could Mewtwo's 'awakening' mean?" The evidence is mounting.
By the way, I'm gonna recommend Provictini's feed: it's in HD, and the signal isn't skipping like in Zephyrsonic's feed.
I'm too lazy to go download the program to directly watch Pokemon Smash, so I'll settle for the Youtube stream. It's always good to see the older episodes of Pokemon I used to love, even if they are in Japanese.
