OK, can we speculate as to what's gonna happen?
All of this in conjecture, as I'm only on book three (and unlikely to continue reading), and haven't read any of the fan pages. But here goes... (Conjecture spoiler alert):
Obviously Jon Snow is not dead. Or rather he is, but conveniently the red witch, who has a habit of resurrecting the dead, is nearby. Notice what his death accomplishes though. Think about his vow to the Night's Watch: "Night gathers, and now my watch begins. It shall not end until my death." So if he dies and comes back, oath taken care of.
Why the fixation on Jon Snow (who has had a really boring story line, IMO)? He's the crux of the story. He ain't Ned Stark's bastard son. He's Ned's nephew by the dead sister and the Targareyan she had a fling with. (Don't really remember this but I think it's in there.) Targareyans have a habit of marrying siblings. Daenerys Targaryen is widowed. Wedding bells. Oh, and she has three dragons she's slowly losing control of. Brandon's a worg (controls animals with his mind). Last we saw of him he was told he'd never walk but would fly. Done. Or one third done. Maybe the Imp rides another. He has that special saddle. The Imp is aligned with Daenerys. I say the four of them come together, probably with others, to rule the seven kingdoms, or maybe we unite both sides of the ocean as well.
Arrya is roaming around aimlessly, as is now Sansa. Sansa's wolf died in the place of Arrya's (King Robert needed a wolf to kill and took Sansa's when Arrya's bit Joeffry). I think that portends that Sansa is somehow going to die to save Arrya. Don't know how that figures in yet. But he haven't had a good Stark killing in a few seasons now.
Just some of where I see all this going.
