The BBC doesn't stick all its money in one general fund and let people make withdrawals as the urge strikes them; it has to be apportioned and justified very carefully, especially in the current environment. The only way BBC One will have spent money on the found episodes is if it's broadcasting something related to them (which I doubt), and even then it won't have been at the expense of the anniversary special, which is a much bigger deal from an institutional perspective. The Moffat quote is interesting. If he can deliver on that, it'll be a great special. But then RTD talked about doing a story that would Change The Character Forever, and it turned out to be "The Doctor's Daughter."
