This episode makes a point that the Doctor is out of regenerations, counting the War Doctor and the Tenth Doctor's regeneration into himself towards the end of Series 4. However, in "The Impossible Astronaut", it was shown that the Doctor was killed for real since he was killed during his regeneration. Of course, it was revealed that that wasn't really the Doctor in "The Wedding of River Song", but it still suggested that he had another regeneration left. See more
