Well, they don't have that many characters.
the two male detectives
the female coroner
They're obviously not killing off Castle or Beckett, and I doubt they'd axe the daughter (she's young, she's cheap, she's cute, she brings the father-daughter dynamic). I can't see where they'd kill of either of the two detectives since they're the "buddy cop" roles. I don't think the female coroner's been there from the beginning. So, IMO, the two best candidates are Castle's mom, or the captain. I think his mom also adds a dynamic to the show (and a comic element) so I think it's going to be the captain. They (i.e. series producers) like to throw new bosses into a show to shake things up slightly (e.g. The Mentalist, Criminal Minds, CSI, Bones).
