It has been revealed by the BBC that, during this year's Children in Need on Friday 20th November, a preview of the upcoming Christmas special will be exclusively broadcasted to millions of viewers. Cue lots of serious music and pained faces!
In other news, it has been rumoured that the transmission date for The Waters of Mars is Saturday November 14th, but this is yet to be confirmed by the BBC. Also, various online sources have said that a boxset containing The Waters of Mars and the last two specials (what about Planet of the Dead?) will be released on January 11th 2010, but again this hasn't had confirmation.
