He's finally back!!
As suspected by all of us (and surprising nobody), you can only unlock him by purchasing both versions of Smash. Which I was going to do anyway, but thanks Nintendo. Except that Mewtwo is DLC, and we don't get him until 2015... so if I have to pay for Mewtwo, Nintendo, I will disown you.
Don't disappoint me.
Anyway, with the new direct a lot of information was given; two more Profiles are on the way, and maybe one or two other posts on the Direct itself. And then, my 3DS review!
