I hope not. The rule is that a Time Lord can regenerate twelve times. This means that you can have thirteen different Doctors. Which they have with Peter Capaldi. I would think that the "twelve regeneration limit" would be better addressed when the Doctor is actually on his final regeneration, especially since you could do some strong character work with how he reacts to the oncoming end. If they change that before it becomes critical, then they lose a potential story edge that they would have.

Granted, I don't want it to be something they explain away at the last second, but I'd prefer to see Capaldi's Doctor have to wrestle with his mortality for a time before they do address it.
