I really, really hope they aren't. It looked horrible, and I don't really think it goes well with already established lore - it is nothing like the Cyrodillic vampires in Oblivion and Skyrim, nothing like the Voikhar mentioned in Immortal Blood and also nothing like the three vampire bloodlines in Morrowind. I think the Daggerfall vampires were similar to Morrowind's.
I agree. It looked awful, & I mean that in every sense.
The character model looked completely identical to the vampire monster thing in those horrible, awful Underworld movies, which is to say it looked like utter crap. It'd make no sense in the lore, it's absolutely nothing like the cultured Cyrodillic vampires, it doesn't sound like Volikhair, or the organized clans of vampires in Daggerfall, & Morrowind. It's not even reminiscent of some of the weirder vamps like in Valenwood, or Black Marsh.
Also, I can't be the only person who's hoping against all hope, that they don't stick flight of some sort in the game, it just seems like a bad idea.
Besides, if you want to play a character who turns into a big, slavering monster & rips people to shreds, play a werewolf.
