David Tennant announces he is leaving Doctor Who at the end of 2009
I'm a bit surprised - If I'd been asked to bet, I'd have put my money on Tennant leaving at the end of 2010, just because I figured that they wouldn't have gone to all the trouble of shortening the 2009 season so drastically to accomodate Tennant's other projects if he wasn't coming back for a full season later. Still, this gives them plenty of time to pave the way for Doctor number 11.
I know lots of fans will be dismayed by this. Personally, I'll only be dismayed if they cast someone terrible as his replacement - I like Tennant, but regeneration is part of the show, and I'm personally ready to see what someone else could do with the part.
I'm a little confused about timing, though. Does this mean we get a regeneration in the Christmas special for 2009? 'Cause that would be a bit of a downer. (Well, if you're a sad fan like me, who always weeps during regenerations.)
