Re: 800th Episode - 2014 Christmas Special (Rumour's/Poss. Spoilers)

I suspect this might episode will conclude some of the plots that have been going since the Matt Smith's Doctor made his first apperance.
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.
