This just in (well, actually in on June 26!) from Cubicle 7: 
Hi there, the cover for Doctor Who: Adventures in Time and Space, the official role-playing game can be seen over at Cubicle 7 and we’ve confirmed the release date as October 2009. Further details will be released soon!
That’s pretty cool. I didn’t play the previous Doctor Who RPG, but I’m a fan of the new series. I’ll be interested to see how this plays out.
