Does Sir Blackadder and sci-fi match?

Richard Curtis is going to write a story for Doctor Who (here is the official statement of the BBC, and here is a nice blog review by the guardian, with an even nicer comment). Although fans are already speculating weather Sir Edmund Blackadder will meet the Doctor or not, I think it's rather unlikely as Rowan Atkinson won't agree to play that famous character (again), and I'm quite sure that Curtis won't want anybody else to play that role. It's more possible that the Doctor will come across a "demon headmaster" ( Terrence Hardiman has already been spotted on set) than with Sir Blackadder.

But apart form this there aren't any news, but speculations. Rose seem to have been seen on set too, but as we know she is supposed to be living a happy life with "her" Doctor in a parallel universe. And come on, Moffat can do a lot better than that. I really wasn't too fond of Doctor Who's last season's final, nevertheless, its (only) positive aspect was that we got rid of Rose, forever. So, thanks to RTD, we can put Rose on the "never going to happen" list.
