Many believe that the punching indicates that it is an upgraded Upheaval or maybe a new ability that is an AoE equivalent and that seems plausible. Looking at the length of the animation, which is pretty long, that could point to it being a GCD ability, so maybe it is a new 3rd step in the AoE combo. We don't really know for sure and so a definitive answer is not really possible.
