Oddly, it seems that they keep getting younger with each doctor.
Maybe they wil get Justin Bieber for the next role. /s

I posted in another thread a long time ago that the doctors were getting younger. And, since the current [Smith] is supposedly the last, the 'next' would be a baby, which would signal the rebirth of the Time Lords.

In related speculation, I would like to see Andrew Lee Potts as the new doctor. We basically watched Andrew grow up in Primeval.
