Actually, you'll get to hear from them very soon... in about two weeks, actually... that is, if you have access to BBC... :)

It is generally accepted that the Hartnell doctor was the first incarnation, even though it's never been stated outright... certainly, he can't be any more than the third, otherwise the Doctor would have run out of regenerations by now. And I can't see Russell T Davies doing anything so crass as prequel stuff during his stint as producer on the show... of course, what happens if/when he passes the baton on, is anyone's guess...
