Yes, exactly. And the BBC are offering Tennant a lot of money to stay on.
Although I don't know what's going to happen next episode, and for that reason I'm looking forward to it!
Want a spoiler for the Christmas special?
My favourite enemies are returning, and about damn time too! Screw Daleks! I suspect there'll be a trailer for it after this Saturday's episode, so it's not too much of a spoiler.
