The Daily Mirror is reporting that the TARDIS interior will be redesigned for Matt Smith's arrival in the TARDIS and the move to HD filming. The Mirror also says that the designers will "improve the quality of the police box exterior", and credits the change to incoming showrunner Steven Moffat, who scripted a line in the 2007 episode "Blink" noting that the TARDIS's police box windows were the wrong size, an in-joke aimed at the Outpost Gallifrey Forum (now the Doctor Who Forum). The TARDIS redesign story has been picked up by the Daily Telegraph, METRO and Digital Spy.
