RTD said he counted as a regeneration, I heard (but I never saw the article)- at least in Next Doctor, the Doctor only seemed to think there was two regenerations left.
The Mighty Moff has final say tho, as it's his baby in 2010 and the issue cant be resolved before then ... now if RTD were to stay in charge, I would take any statement to the press that it doesnt use up a regeneration as a sign than in an already written but not finished ep, we would see consequences meaning it does use one, as that's how he likes to bait reporters for ratings
- tho most of us are on to him by now.
The more I think about it, the more I hope it does, as it increases the likelyhood that Moffat is the one in charge of figuring out what happens when the Doctor uses up all his lives, and he's creative, smart, and likely to find a solution to make the geeky heart happy
But it still is one of those cloudy issues that we can debate about for a few years till they prove us all wrong with their own idea of what happened.
(Also I'd make a thread and do a little dance to say 'The forum is back! The forum is back!- but since no one can read those threads unless they already know it's back ... well, not much point. But much thanks to Henry Von Stanton for fixing the internet for us, and for Hilary for poking him in the elbow till he complied)
