Other timelines

 * Mickey Smith, Jake Simmonds and Pete travel from a parallel world back to the Doctor's universe.
 * Due to time differences between the two worlds, they appear in 2007 in the other world. See also Pete's World.

Real World

 * The 5th series of Doctor Who is scheduled for broadcast this year, consisting of 13 episodes with Steven Moffat taking over from Russell T Davies as executive producer, and Matt Smith taking over the role of the Doctor from David Tennant. Production of the season began in 2009, but is expected to carry over into 2010 per the precedent of previous seasons.
 * BBC Books, if it decides to continue its line of original novels, will presumably retire the Tenth Doctor Adventures upon the departure of David Tennant and launch a new line, presumably to be called the Eleventh Doctor Adventures.
 * Assuming it is renewed, production of Series 6 of Doctor Who will presumably begin in the second half of 2010, for broadcast in 2011. As of January 2009 it has not yet been announced as to whether this will include another Christmas special.

"Early 2010"

 * According to media reports in October 2008, the final "gap year" special episode of Doctor Who may not be broadcast until early 2010, contradicting earlier reports that they would all air in 2009. This final special, whenever it airs, will be the last under the watch of producers Russell T. Davies and Julie Gardner and the last to feature David Tennant as the Tenth Doctor; it is not yet known whether the actor chosen to play the Eleventh Doctor, Matt Smith will appear in the special as well.

March

 * 26 - Fifth anniversary of the return of Doctor Who to television.
