I'm going to have to agree with him, despite having no proof.
I just can't get around the fact that there is not another female org. I suppose those guys are sexist ... but w/e.
I really believe that EM is that short blue haired guy at the end of the trailer, which means that leaves about a couple more spaces for the female unknown and the new long-haird bue-haird unknown.
At least I will beleive that until I get some hard proof that it isn't.
Just in case, I am NOT saying that EM is confirmed to be the blue-haired unknown, i'm just stating my opinion.
EDIT: Wait, do they have the same voice? ... ...
Oh well, meh ...
