Surprised someone hasn't posted this already, but hey.
This is purportedly regarding the final episode of this series..
Probably best not to get too excited, as this was most likely posted by an overly enthusiastic fan, hoping that if he post it up, it'll come true?
Spoiler:
IMDB has David Tennant's final appearance down as 8 October 2011.
Episode 13, series 6 (Title unknown)
Starring: Matt Smith, David Tennant and Peter Davison as the Doctor..
Other characters included are: Amy Pond, River Song, Rory Williams, Winston Churchill, Young Rory, The Silent, Dorium Maldavar, Malohkeh, Anderson , Young Mels and Dr. Kent .
No hint of the story (Shock, horror)
Nothing on Wikipedia though, they still have his final appearance as 2010.
Maybe the poster doesn't have editing privileges enabled over there

Really can't see the Moff going to all the trouble of swearing anyone in the know, to absolute secrecy, only to give IMDB the info, but it would be nice.
