Okay, so all the Docs end up in the current TARDIS from the pictures. Obviously that's probably because they don't have the set for 10's TARDIS any longer
10's is part of the Doctor Who Experience in Cardiff and was used for part of the filming. It's only missing some wall and celing so filimg at certain camera angels would be no problem. One of the new photos shows Tennant at the controls and is shot in the direction of the wall and doors that remained as part of the exhibition (I saw it when it was in London).
