This article about last year's Sarah Jane Adventures story, Death of the Doctor, suggests a gentle shift away from the tradition of 13 generations per Time Lord.
The story features the late Elisabeth Sladen as Sarah Jane Smith, Matt Smith as the Eleventh Doctor, and Katy Manning reprising her 1970s role as former UNIT gopher Jo Grant.

“And so to the really big news. A lingering problem since the Who revival has been the trouble with regeneration. Back in the olden days (The Deadly Assassin in 1976 to be precise) it was established that a Timelord had an upper limit of 13 lives. Eleven Doctors in and the clock is ticking – nobody wants to be a slave to continuity, but something needed to be done about it. And here it is. Crawling through the ventilation shaft, Clyde asks the Doctor how many times he can regenerate. "Five hundred and seven." Audacious hardly covers it. Judging by an average stint of 3.2 years per Doctor, which gives the series a shelf life of 1622.4 years to come. No immediate danger – and surely this is better for the jeopardy of the show than previous reports that the Doctor was now immortal?”
