Doctor Who premieres April 15 on BBC1 and BBC America.
A decent portion of Who fans believe that Capaldi had more than just one season left in him and that his departure is somewhat premature.
Of course one question hanging over Bill as Doctor Who heads into season 10 is how long she might last in the role given that both Peter Capaldi and Steven Moffat will be leaving after this batch of episodes.
It would be a shame if by the end of season 10, the same can be said of Bill Potts.
