Re: 50TH Anniversary rumor
No doubt the tabloids will be camped outside for when they film the 50th Anniversary episode(s) ready to take pictures. Of who will likely be in it.
So no doubt who's in it will leak long before the episode airs.
On the continent of wild endeavour in the mountains of solace and solitude there stood the citadel of the time lords, the oldest and most mighty race in the universe looking down on the galaxies below sworn never to interfere only to watch.
