I've spoken with the developers and they let me know that they're not satisfied with the impact the windfury totem change is having on current end-game content balance, and plan to undo the change. Please remember that the testing phase of any patch is precisely to test such changes and evaulate their possible impact on the game, whether or not they eventually go into the final release build.
In short, no change to Windfury Totem is planned at this time.
It shows that Blizzard listens when given hard evidence/massive whining of an unbalanced nerf.
For all we know they arrived at it via thier own means. Unless they say one way or the other we'll never know. I may be wrong but I do assume that, despite what I feel is a total lack of feedback (communication) on their part, they are experienced enough developers that they know better than to jsut throw this shit out there and never look at it again assuming that it's going to work in practice just like they envisioned it would in thier heads.
