User blog comment:Goddess of Despair/RWBY and it's connection to the supernatural/@comment-5230279-20130304004612

I don't think they are vampires, here are my reasons:

1.Weiss uses Magic to increase her speed/strength

2.Ruby wears crosses on her costume. (the Cross is know to cause Vampires Discomfort)

I can't imagine Monty following the Vampire craze that has been over done since twilight.. and from what Kerry and Miles have been saying about the story, I don't think it should be taken so serious. Since they are working as a team it wouldnt make sence for Vampire and Were/Beowulfs to work together. but it's an interesting theory :)
