Fantastic. I couldn't have hoped for a better result to my post last week! (Because it was obviously down to me...).
Here's what no-one else has thought of, though...
This means that David Tennant must be stepping down too. Do the math.
- Tennant will be filming this year's Christmas Special now, then from July to November he's playing Hamlet at the RSC.
- He'll be filming the four Specials from Jan 2009 (ie four double length episodes, the equivalent of eight episodes).
- Moffat's first season is due to start Spring 2010, thus filming will have to start in the summer of 2009.
Unless Tennant plans to be filming Who for the entirety of 2009, he's not going to be The Doctor in Moffat's series (unless there's a mid-season handover...).
The new Doctor speculation starts here.
FanboyGeek Keir suggests Julian Rhind-Tutt. I think he ticks all the right boxes...
