Yeah, i don't think Ron's going to die ... he's just been a part of everything for too long. I know people may say that so has Hermione, but when you think about it, Ron is Harry's bestest friend.
Eg. GoF- "There was a lot less laughter and a lot more hanging around in the library when Hermione is your best friends" (Or something like that)
So the only way i can see him dieing is if he does something incredibly heroric, that will be his thing for the rest of his (Well, not life, but you know what i mean!)
Because throughout his years at Hogwarts, Ron just been trying to find out what he's good at-what's his thing? Because all the other Weasley brothers do-
Bill-Head boy
Charlie-good at outfoors/care of magical creatures (And dragons of course!)
Percy-Prefect
Fred/George-funny/good at pranking
Ginny-acomplishment in the bat bogey hex/fierce personality/follows things through.
But what does Ron have? Chess.
Yep, just chess.
Others see him as the "Side-kick" but i see him as a acomplished chess player.
Ron needs to find his thing, which i think will be bravery (Which Gryffindor is all about)
So Ron will either die doing something heroric, or will do something heroric that will be remembered forever and all ways.
I hope he doesn't die *Crosses fingers muttering "Please please please don't let him die O mighty JKRowling!*
The other i think will die is Neville (Though i don't want him too, he deserves a happy life). I just see him dieing, that's all (I suck at backing up with evidence)
O let mighty Ron live on! (Hey that rhymes!)
