Absolutely, it's high time the doctor had a new lease of life. How are you with one-liners and straight-faced, pseudo-scientific explanations? And more importantly who would you pick to be your assistant???
It doesn't matter about the age of the Doctor in the new series as I'm sure they will aim for a five doctors story once they have 5 doctors in the can, at the moment they only have 3 of the new ones, but hey that will be cool, Bard could be the 4th and I could be the 5th.
