On my current main character in Skyrim, I'm a werewolf because I was originally a warrior, but now I'm more magic orientated with the 100% reduction to cost of restoration and destruction magic (kinda cheap, I know but meh, I hate the slow regeneration of Magicka) Anywho, currently i've done the Totems of Hircine, and with the news of Dawnguard I went to cure my Werewolf blood to become a vampire, but I don't have any witches heads, nor can I find any in the original cave. I also heard that once you've done the Totems of Hircine quests (I've got 2/3 totems), you can't cure Lycanthropy.
I really hope that they add a quest to give you the option to convert to a Vampire, or fix it so that you can cure lycanthropy no matter what. Is there any sort of news for that? Cause I'd hate to not be able to use that sweet new vampire form they showed =\ And I don't really want to start again / use my other character.
