The big thing I'm pointing out with the while thing is that the stances they use while fighting isn't the stance monk has been using and the style of their moves have their differences from monks as well. It's all well and good to say they're monks in that trailer but if they are monks then I would have to say they're re-doing monks style of fighting.

If you've ever watched Yda when she takes up a fighting stance she's in the standard monk stance, not one of the stances they were using in the trailer for the girl. If both her and the guy in the trailer are monks then I would have to say that monk itself is getting an overhaul. The guy might be a monk but the girl is something different, she doesn't move or fight in the same type forms that monk does.
