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).
I see your reasoning. I just want to point out that Lanie, while not having always been the coroner featured on the show, has been there since the beginning. Personally, I'd hate to see any one of them go.
Now, on to hulu to watch last night's episode.....
