So we wanted to be sure that you all got to see this before Blizzard has YouTube pull it. You probably have about 30 minutes at best. So go at it! The video below the break shows some introductory worgen moves from the recent Russian IgroMir 2009 demonstrations Blizzard had setup. Video is typically against the rules at these things, but a leak is a leak, and this should give players a good view of it.
Of particular note is the animations at the end of the video. The /welcome animation is a worgen pointing, waving, and then getting down on all fours to sniff the air in-front of him; as if to smell the nether regions of the person being greeted as canines are prone to do. There is some discussion if this it worgen idle animation at the wrong time, or if this is part of the overall /welcome animation sequence.
Unforunately we don't know, but we're all having a good laugh over it. And now you can do.
The goods after the break, while it still exists.
