I am of school of thought that Jaime will not die, I think he payed his "dues" when he lost his hand. But loads of others, yes! ** sigh **

And Sandor is bound to die IMHO; and in this I believe mostly because of that prophetic conversation he had with Sansa. Also I believe he is going to be the one to kill un-dead Mountain (and a combat with Mountain can never end well, as Oberyn Martell proved).
