Does anyone know if any more has been released? I have seen the http://www.youtube.com/watch?v=oZqXKZOS2jQbut has anyone seen any more footage or is that all we get?

There's been quite a bit, try searching youtube. Still more to come as well.

Yeah, what patti said. Search specifically for "Dawnguard e3" should yield some good results for gameplay.

There is new gameplay on gametrailers and G4 showing a player in riverwood using new powers and perk trees.

[censored] off with the misleading title, thx

Look for the other forum threads featuring G4TV and GTTV gameplay demos from yesterday.
