Even people who don't like elderscrolls would probably pick it just because of werewolves. If they had them in right now, not announcing it would be a very stupid business move. I would pre order it immidiatly if they had the werewolves.
Vampires are more popular than Werewolves are, and I don;t see the run-of-the-mill Twilight fan racing to pre-order since they were announced.
Maybe its because;
1. Being a werewolf or vampire is a small roleplaying facet compared to such a huge world inhabited by Dragons and a myriad of Factions. It's just another option to the already innumerable options of character customization. Not a big deal.
2. The game designers read our threads here. They are probably very aware that Werewolves are much more wanted than vampires. They would probably keep it a surprise.
3. This is kind of irrelevant, but Werewolves are said to make SKyrim their homeland.
I'm just discouraged they're hasn't been an announcement yet. Which either means they're keeping it a surprise, or they don't want to disappoint fans prematurely.
Its also discouraging that no one ran into a werewolf in any demo.
