I think Clara is going to call it a day at the end of next week or the Doctor is going to call it a day for her... The pregnancy predictions could be true or maybe The Doctor thinks that she's grown to be too much like him and he wants to save what humanity she has left, because that's why he loves his Companions. He adores humanity.
But I'd love for them to take the opportunity to have a former companion be a true recurring character. My one problem with the show is that when a Companion leaves, they rarely come back and in NuWho, it's almost as if they have to completely throw the baby out with the bath water and make them either irrevocably broken (The Ponds, Donna) or create some reason as to why they can never come back (Rose, Mickey). It'd be cool if Clara leaves stops making regular appearances on the TARDIS and is relegated to one or two appearances a season allowing her and the Doctor to maintain their relationship while he travels with a new crew.
