'io9's Comic Con Interview

And, last but not least, also 'io9' did some questioning of the 'Who' cast, with some rather interesting stuff. 

First of all, Moffat promises to tackle some of the yet unanswered questions in this year's Christmas special. Maybe not all, though. However, I'm a bit disappointed that he does not have any plans of bringing River back. We're still waiting to find out why she knows his name. And I thought that Matt Smith's last episode would have been the perfect opportunity for that; with all the hints at the Doctor's name. But maybe that's just the Moff doing what he does best: lying and not giving any teasers away.

Then he talks about the despairing fact of not having learnt anything since 2oo5 when he started writing for 'Doctor Who'. Its episodes are so different form each other that he wonders how he's been able to write so much for 'Who' and every time still needing to figure out anew what's working and what's not.

The second part of 'io9's article is them talking to Matt and Jenna about if and how Clara knowing 'everything' about the Doctor's past (and his future?) changes the relationship between the Doctor and his companion.
