The source from the original site, hope you have decent translation software:

One of the many threads on the Bethesda forums about it. http://forums.bethsoft.com/index.php?/topic/1242636-recent-update-on-werewolves/

The translation of the section in question, someone may want to check for accuracy:

Is there an idea to add werewolves into the game as dlc?

"Maybe so, yes. We currently have no werewolves in the game, but it's definitely something to think about. What we do have in the game, are vampires. How progressive you will play the vampire, the more people will begin to attack you in cities. Also, the vampire is much weaker during the daylight."
