Re: Er ... Dr. Who canon ?????
Can't tell if you're just going for a reaction, but I'll bite:
1) Traditionally, the Doctor had 12 regenerations, i.e. 13 incarnations. And that was stated fewer times than people think it was, and even contradicted on an occasion or two.
2) RTD didn't have anything to do with breaking the limit. Moffat did that, mainly because the Doctor was running out (too long to explain why) and he had to.
3) Fifteen years olds lose interest in things all the time - in a few years he'll be back with the nostalgia goggles on like everyone else.
