All I know is that we need Alexander Skarsg?rd (Eric from True Blood).

Preferably playing the patriarch of the Volkihar vampires.

I don't care if there's no big-name voice actors, as long as there's some variation in the voices. I hated how the cast was so limited in Oblivion.

If Fallout: New Vegas is any indication, Bethesda's capable of providing the budget of providing a varied voice cast, with plenty of well-known actors. I think we'll be in for a treat.
