Steven Moffat has hit out at rumours that Doctor Who's episode count is being cut by the BBC.

Speaking to The Daily Beast, he called the rumours "absolute nonsense".
"First of all, we are airing in 2012," he insisted. "The only thing that's happening is that we're moving a bit later. There's lots of reasons for that that will become clear quite soon. It is certainly not a reduced episode count. Do you think the BBC would really let that happen? With an average audience of 10 million? You're not going to reduce a show like this. The opposite is going to happen, in fact."
Moffat also said that answers to all the loose ends will be given by the end of Series 6.
"Answers will be given. We're not playing at really being Lost. You will know what's really going on on that beach [and] you will know the truth about River Song, which you don't know yet. It's pretty much answer, answer, answer in a way. By the end of episode 13, new things will have begun, the great thing about the River Song conundrum is that every time you get an answer, it makes you ask another question."
He also stated that Series 7 won't be as arc-ed, and will have more stand-alone stories.
"This is the most arc-intensive we've ever been and I'm throwing the lever the other way next year,"
So it seems Doctor Who will be back for a full series in 2012, answers will be given by the end of Series 6, and the show won't be driven by story arcs as much.
