In a brief talk with Radio Times, the current producer and writer of Doctor Who, Steven Moffat, spoke a little bit about the season seven of the show, and that the 50th Anniversary in 2013 will be the best time for a fan:
“It will be returning in the Autumn – not exactly saying when – for a long run. I’ll just say it’s at least 14 episodes. Obviously we start in the Autumn so the Christmas special is part of the run.”
“Oh dear god yes! I think honestly, saying this as a Doctor Who fan myself and knowing a certain amount of what’s coming, there will never be a better time to be a Doctor Who fan! I absolutely promise that!”
