There's no way we're getting to find out the name, it ruins the whole concept of the 'Doctor Who?' if we know the answer is 'John Smith'.
I think this episode is going to be the last one before The Library in River Song's timeline, and thus is the time she finds out his name. Bit worried about her future in the show to be honest, she has become a bit of a drag in recent appearances but she's still a great character overall.
