EA released 2 new screen shots. They are called Vampires but it's unsure if they are a real Creature or just modeled like a Vampire.
Update: EA has clarified that while you can indeed make a Sim that appears to be a vampire, you cannot actually play as a vampire.
Fansite Alalasims went to see a Sims 3 presentation and wrote down lots and lots of facts.
