Being that I just got into Doctor Who last year, I'm not very familiar with their marketing scheme. It seems to me that once it begins they just continue short teasers non-stop. Personally I don't think that's needed. It's not like people aren't going to watch the premiere, but why given them ammo on a Doctor they're already on the fence on? At any rate here's a teaser with what people are speculating is the Davros, the creator of the Delaks. Personally I'll just wait to find out. http://www.youtube.com/watch?v=LbX4tNG_k3s
