New Who?

There have been several rumors this year that a massive trove of missing Doctor Who episodes have been uncovered. (Backstory: The BBC, never knowing about home video, DVD's, a massive fanbase and the like, destroyed many of the early episodes. However, on occasion, missing episodes turn up because they also sent copies out to other countries, and not all of the copies were returned.) Alas, most of these rumors have been squashed. Until now. This rumor is gathering a ring of truth with this story from the BBC itself. What might be in the treasure trove? A guide.
