For me Kit will not longer be on the show but Jon is still alive. When I read the book I thought that Jon will warg to his direwolf or someone who is near him, that's why we at the begining we have a chapter about that warg that goes from body to body. For me it was a foreshadow for Jon storyline. Remember in the book when Maester Aegon told Sam about how Mel got everything wrong and that Stannin was not the chosen one? I think that she'll be on the wall so she can see Jon's resurrection or however he come backs to realize he's Azor Ahai. I don't know about Davos tho...
