Yeah, I know, I'm going from not posting anything for the longest time to rushing in with info about something where all the details aren't fully out there yet...but it seems that there's going to be a way to have the original Mewtwo playable in the arcade version of Pokken, in addition to having him on the home console!

This marks the second time that a game was released without Mewtwo initially playable, and then he's added in after the fact.

I'll update this journal once the full details are posted somewhere as to how the special event works.
