This is a Youtube video i stumbled across a day or two ago.
It its quite poor quality and i am not sure of its authenticity as far as Beavis goes;
However it is from the latest WotLK patch, and quite fun to watch

Silly and entertaining at the same time.
I will certainly miss 2H Enhancement in Cata
Edit: As far as i can see, this video was made before the 4.0.1 release, so it is not affected by Cataclysm changes.
