today's media reports, the Radio Times are saying on their website that the rumoured find of Doctor Who missing episodes will be released for purchase on Wednesday morning. The episodes are claimed to have originated from a find in Africa and have been digitally remastered for sale to the public.
The released episodes are believed to be from the Patrick Troughton era, and will go on sale over download sites such as iTunes. Little more is known about any further finds, but rumours seem to hint that further announcements will be made as we get closer to the day of the anniversary itself.
The Radio Times seem confident about the validity of the rumour, retweeting it many times. There latest draft of the article labels the news as "exclusive."
Update: The Mirror have also published this news, adding more details, though given the fact that The Mirror are notorious for making things up, none of this can be confirmed.
According to The Mirror, there will be a press screening on Tuesday with a BBC's Spokesman stating "there is a connection" when asked about the reports of more than 100 episodes being found.
There may very well be something planned for later in the week that the Mirror jumped the gun on (probably without asking the BBC for permission...). The Radio Times report could therefore be an exercise in damage limitation; they're pre-empting further revelations by just saying outright what was going to be announced. The possibility also exists that this could be a smoke-screen; you still can't buy the latest two missing episodes from "The Underwater Menace" and "Galaxy Four" (yes, we know that's a Hartnell story and not a Troughton one) on Itunes. People have been asking the BBC to distribute these two episodes publicly since they were found, so announcing a public release for those now might help confuse the issue for a much bigger haul, for which rights negotiations might still be ongoing. A way to give the BBC a bit of breathing space until they're ready to announce their own news.
The best way is to take all this with a pinch of salt. The BBC haven't announced anything on the Doctor Who website about any of this yet, so nothing is 100% confirmed. Until they do, we'll still be sat on the side of caution.
