"The final days of the Ponds are coming during the next series - that story will come to a heartbreaking end. Then the Doctor will meet a new friend"
Matt Smith, also attending the press screening, commented:
"The show will miss the Ponds, brilliantly played by Karen & Arthur, but the great thing about Doctor Who is its ability to change. It's very disappointing - but this show is about change and regeneration."
More details of the new "friend" have been promised by the BBC tomorrow - but the role has not been cast yet.
The Moff also said that he thinks River Song WILL return...
