"The Doctors embark on their greatest adventure in this 50th anniversary special. In 2013, something terrible is awakening in London’s National Gallery; in 1562, a murderous plot is afoot in Elizabethan England; and somewhere in space an ancient battle reaches its devastating conclusion. All of reality is at stake as the Doctor’s own dangerous past comes back to haunt him."

Now it's only twenty days away, let's see what we know:
--> For all we know only three doctors will really appear, but there could be more, couldn't there?
And is it ten's metacrisis duplicate or the tenth doctor from the past? And who is that doctor between eight and nine?
--> We don't know which companions will be in it, but we know for sure that Clara and Rose will appear. While Clara's appearance is logical, Moffat tells us Rose will also have an important part. Sarah Jane is in the trailer, but sadly her appearance is no longer possible except in archive footage.
--> It's about some very significant day in the doctor's past, but will the entire movie be set in the past?
--> It has something to do with paintings, but that may be a completely false lead.
--> Who will be the main enemy? There have been Zygons, Ood, Daleks... in the trailer, but there have also been a lot of doctors and Sarah Jane, so I am not quite sure if that tells a lot.
I will add it if I remember something else or the BBC gives us more information.
