you're not completely right volkihar -WE- vamps already exist, im a volikhar dovahkiin and my eyes dont glow
Nope. PC Vampires in vanilla Skyrim are Sanguinare, even if infected by a Volkihar Vampire. Bethesda didn't have the Volkihar strain fully fleshed out yet by the time the 11/11/11 deadline hit, so they just tagged the Volkihar Vampires with the Sanguinare Vampiris strain. We are already seeing Bethesda sneak in the groundwork for Vampirism improvements with their patches.
We've also seen concept art of Lamae Beolfag before Skyrim was released, and she's apparently not in Skyrim yet. She was planned to be the main antagonist in the Dawnguard expansion.
