I'm trying to stay away from spoilers, so the following paragraph contains absolutely nothing grounded in content from the books (it's not spoilers unless you assume I'm clairvoyant). Based on the way the series has developed, GRRM clearly has no problem killing off anyone at any time. There are simply too many characters left that I like to assume they'll all escape unscathed for too much longer. So, while I have no idea whether or when they'll die, I'll preemptively say that I'm going to miss Tyrion, Tywin, Olenna Tyrell, Jaime, Arya, Sandor "The Hound" Clegane, Bronn, Daenerys, Cersei, Varys and Davos. And probably Littlefinger, more because I like Tommy Carcetti than anything else, and he seems to be turning into Batman (I'm just going to speak all my lines in a harsh whisper). Joffrey is a righteous fuck, so he'll live forever. Oh, and motherfucking Hodor. Hodor is the man. He always knows exactly what to say. Which is not to say that the other characters aren't any good, but they aren't nearly as entertaining as that lot.
