one rumor confirmed!

 Quote:
Of two "Doctor Who" questions, Gaiman answered that his favorite in the lead was #2. "Patrick Troughton was my Doctor," he said. Later, when asked whether he'd ever want to write an episode of the series, the audience began tittering before Gaiman could respond. "I would love to write for Doctor Who so much, that I wrote an episode," he said, recapping the long-rumored and recently-confirmed project. Gaiman said that his episode was meant to be the eleventh of the current season, but budgetary constraints pushed it to series six, "when they have more money." He also added that, now that show runner Stephen Moffatt has confirmed the existence of the episode in interviews, the writer is free to reveal all of the details Moffatt has: "It will be on television, it is in color."
