If so, is there a video?

2 so far and 2 more coming today.

Head to gametrailers and G4

Yes gametrailers and G4tv..or just go on youtube,people have probably uploaded them by now.

I must be an idiot because I cannot find anything on gametrailers.

Go over to the dawnguard discussion thread. They have all the new info gathered in the original post. I have the werewolf perk tree in my sig.
