Re: 7X04 The Power Of Three (Grading/Discussion) (SPOILERS!)
It's already been confirmed by BBC, Moffat and Matt Smith that 2013 will consist of the remaining S7 episodes, an undisclosed number of specials similar to what we had in 2009 to celebrate the 50th anniversary and a Christmas special. There won't be another full season until 2014.
