I have no idea but I got so pumped when I saw the preview!
My guess it's something of a shifter-vampire cross.
Well, since they already addressed the "how to cure werewolf-ism" in season 2, I hope its something they can cure.
Although, if Sam is half demon, why not have Dean be something more supernatural? A werewolf, he'd only be doggie style once a month, but still have all the pluses of his condition every day.
Vampire...he'd be dead for eternity and have a large variety of weaknesses. But he is gorgeous enough to be a vampire and is very charoismatic.
Shapeshifter would be pretty awesome but then I don't know if he'd be able to hold his favorite hand gun (it looks a bit of the silver variety).
Ahhh, the possibilites! Atleast he's not something mutating like that man/worm guy in season...3? "Manburger Helper"
