Remember when Arya asked whether they could bring her father back to life after he was beheaded? The fact they showed his wolf's head on Robb's corpse says he can't be resurrected, but it's not the end of House Stark. Blackfish is still alive, too.
I have one fear, though. At the end of the day, is this series going to be reduced to a version of Walking Dead? We've seen enough of the Whitewalkers and the wites, and the glow in the dark eyes, and that army of dead people on rotting horses. So is this going to end up as a Zombie war?
They'll have Jon Snow, Mance Rayder, Stannis and Jamie Lannister, Tyrion and Dany, and her gang fighting the zombies? I mean next season Will we see the further adventures of Arya? Not much going on there unless she and Hound become hired guns, killing people for a living.
Sansa and Tyrion ,and Jamie and Cersei will all have to deal with Daddy. Little Finger and Lysa will be marginally important,or not at all, and maybe Varys will emerge as a real behind the scenes power if Tywin doesn't kill him.
I believe Joffrey's days are numbered, but not sure who, how, or when he leaves us. My guess is Joffrey will get the same speech from Granddad as Tyrion got, and he will make Margaery pregnant. While she's giving birth, Joffrey has an accident, courtesy of Tywin, and he's done for.
In any case, the three focuses next year will be on Jon, & possibly Stannis, and the Wildings at the Wall, the soap opera intrigues of Kings Landing, and the continuing march of Dany the Liberatrix. All the rest will be diversions. That's my prediction.
