Doctor Who executive producer Steven Moffat has offered some new details as to what to expect from the new series of the sci-fi drama.
Writing in the programme to an Australian Doctor Who concert in Melbourne entitled the Symphonic Spectacular (staged on Saturday 4 February), Moffat states:
"Doctor Who's 50th anniversary is coming. In Cardiff, we're gearing up for the biggest, the best and the most ambitious season we've ever made. There will be shocks, surprises and heartbreak - the Doctor is about to say goodbye to his very best friends, Amy and Rory.
"And then he's about to say hello to someone very different - the Doctor is going to meet someone very new in the very last place he could ever have expected..."
So what does all this mean for the Time Lord (Matt Smith)? Any theories and comments would be most welcome.
