It's clear Jessica and Hoyt will end up together, as will Jason and Bridgette. Everyone else is already paired off. Really the only questions are, will Bill survive, will Sarah/Noomi survive, and will they try to pull something shocking like letting Pam get killed. I'm not expecting anything like that. I'll be even more surprised if Sookie dies.
I doubt that they'll create a spinoff, at least not on HBO. Doesn't seem like HBO's "style".
