Whirly orange skill in Monk Full Gameplay video

I just realised I saw this whirly orange skill being used several times in the video here at 1:21, 5:34 and 10:30 with a very distinct "click" sound.

Anyone know what skill it is? It looks like some kind of self-buff but I have no idea which one

EDIT: For those lazy ones, here are a couple of pics of the "whirly orange" skill (I know its not whirlwind btw):

|||No way to really know. Unless someone that went to Blizzcon used the skill and remembers the animation for it. One of the skills like Battle Rage that you have to activate but isn't a shout.
