Yeah pretty much, I just want them to add in the new feeding animations, and the actual Volkihar tribe, like maybe they come out of hiding and start fighting with the Order for taking their name.
Order would kick their teeth in! And then try to usurp the Thalmor!

And who knows what else DLC could unlock, I mean, there has been a large Werewolf DLC in Elder Scrolls, maybe a Vampire one may be in this one.
Bloodmoon was all about werewolves. Dawnguard could be all about vampires.
Either this leaked info is fake or real. Check it out: http://pastebin.com/7skB5Gmu
Edit: Its fake, I think. "Just like we did in New Vegas". Bethesda did not make New Vegas. So it's bullspit.
