Right, for us brits there's just one week left until we supposedly find out the true identity of the mysterious River Song, so this is the last call to get your bets in! Also any theories on what's going to happen with Amy's baby? Let the mindless nerd-speculation begin!
I think it's almost certain that River will have a relationship with the Doctor, no guessing needed there. But how does she fit in to the whole scheme of things? Fire away with your best ideas! And now the old Doc' knows he's going to die, Well done Amy!
Also has anybody seen the cast list on the IMDB for episode 13 of this series? Apparently David Tennant is billed on it. Not only that but above Smith! Also Peter Davison is on there, but at somewhat of a lower position. I think that information should be taken with a pinch of salt at the moment though.
EDIT: Here's a link for you lovely people;
