Another 20 years of Doctor Who?

As cult television show Doctor Who is about to return to our TV screens next month creator Russell T Davies has said the show could continue for another 20 years! Obviously the current Doctor David Tennant wouldn't play the main role for all that time and around the internet many people still think this will be the final series in which he plays the role as the time lord.

Russell T Davies said "Doctor Who is now one of the BBC’s biggest flagship shows and this sort of pattern will guarantee it being on air for 20 years. It’s no good looking at that US TV pattern of making things for seven years – that’s not going to work. Who wants it to die after seven years? It’s much bigger than that.”

“It needs looking after in the sense that it needs pauses, it needs its legend revamping every so often. If you build these pauses in now and say this will happen - it’s literally a 20 year plan which can’t be guaranteed as different people will be in charge in years to come. But if you present them with something rock solid that’s working and has a unique transmission pattern that shouldn’t be interfered with, then it will stay.”

I'd imagine that it would become too stale after that long of a run. Maybe if they had a few years break halfway through then maybe Doctor Who could continue for another 20 years.
