Actually, Marcus, they'll start shooting the new series this summer and he will still be 26 then... While I agree that age doesn't make him a kid still, I don't see how he'll be able to pull off a 900 year old Time Lord. Especially after what the Doctor has gone through recently, I don't see him having enough experience yet. But I haven't seen him act in anything, so I'm only judging by what I've seen online tonight.
I'm probably also prejudiced since I'm rather taken with David Tennant as the Doctor. I'll be sorry to see him go after the specials.
