Peter Capaldi’s time in the TARDIS could be coming to an end, in a recent interview, the current Doctor speculated that the forthcoming series ten might be his last.

"This could be my final year – it's terrifying. I love Doctor Who but it can be quite an insular world, and I do want to do other things. There will come a time when this is over. But I knew that when I started. I was thinking about my regeneration scene from the outset. That's my terrible melancholic nature. When you accept the job you know there'll come a day, inevitably, when you'll be saying goodbye.”

After a somewhat bumpy series eight, the recently concluded series nine was a blistering return to form with stronger scripts and Capaldi settling into the role with electric results. If the next series is the end of Capaldi’s time as the mad man in a box, then the search will be on to find his replacement. 

Steven Moffat will return as the head writer for his sixth year as showrunner, there have been rumours that next year’s episodes will be split into halves, there have also been rumours that we won’t be getting a full twelve episode run in 2016. Should these be the final adventures of the Twelfth Doctor (technically thirteen), then we could be in for a batch of specials spread over two years. Until The Moff confirms what’s going on, we can only speculate. The again, as Moffat takes a certain glee in toying with fans, we won’t know for sure until the BBC make an official statement.
