Who'll be the new Doctor Who?

"Doctor Who" fan extraordinaire Ross Ruediger pointed out to me that David Tennant won't be continuing as The Doctor after the five specials that will air over the next year.

While Tennant has been superb in the role (even most old-school "Who" fans consider him one of the best Doctors ever), it does make some sense for him to move on now. Russell T. Davies, who resurrected the franchise a few years ago, is also leaving, and, as we all know, Steven Moffat (responsible for some of the best Davies-era episodes like "Blink" and "The Doctor Dances") will be taking over. We know that Moffat can write for Tennant, but it's a trademark of the franchise that a new actor takes over the role every few years.

Even before Tennant made his exit official, some fans were speculating that, whenever he left, Moffat might bring in one of his old leading men to replace him, with James Nesbitt from "Jekyll" and Richard Coyle from "Coupling" mentioned most often. I'm not incredibly plugged into the British TV scene, so let me open it up to you all: who would you like to see as The Doctor come 2010?
