` :Have there been any kinds of statements to this effect in articles or anything? I'd be hesitant to do so without an official statement, as they could've been simply reusing a clapboard from Chris Eccleston's time, no? Plus, I don't know whether what it says on the clapboard should be treated as official - heck, IIRC, in some of Tennant's ``video diaries``, there was at least an episode or two whose name changed between filming and air. Gah, I just realized - not to shoot you down, but without an official statement from the BBC (or reports in other RS like the media), I don't think we can use visual evidence from the clapboard - I would argue that runs afoul of WP:OR, particularly WP:SYNTH.  `
