I'm not buying that she's a dancer. I don't believe they would show new jobs in a trailer, at least not so early (considering that wasn't the whole trailer). I could be wrong, but it doesn't sound right to me. To me she a monk that's just more graceful (as women tend to be thought as graceful). Personally, I believe trailers give sneak peeks at possible story in the game. Since it's going to be heavily monk influenced, who's to say it's not a little peek at a possible scenario of one of the future monk quests, and you fight this lovely lady to learn new skills that make you more graceful? Since it is a small portion of the full trailer, I believe both characters are monks. Just as we saw dragoons in the HW trailer, we are obviously going to see a lot of monks in this new trailer.

I want dancer more than anything, but the blonde lass doesn't scream dancer to me.
