Do you guys think Vampire/Werewolf book series are played out?

Unless your book is a totally unique and different concept than yes. It's WAY over done. Sort of cliche. Just give it a few years. You've waited three, and it most likely needs to be re-written and editted. So you probably still have at least two years before publication so the vampire werewolf thing may have worn off a little bit by then. Just keep trying!
