Re: Are regenerations still capped at 12?
If the Doctor's life continues beyond the regeration limit it'll be up to whomever's in charge of the show at the point. I find it's best not to think of such matters and just to enjoy the Doctor as is. For right now now gives the Doctor's life and odd sense of realism, not knowing how long he'll live now it a good thing to me anyway.
