Professor Bainbridge makes a good case that Harry Potter is a goner in the 7th and final book.

Indeed, most great stories end with the world being redeemed by the hero followed by the death or departure of the hero. Moonglum's sacrificial death to allow Elric to blow the Horn of Fate followed, of course, by Elric's own death. Frodo's departure to the Undying Lands. Anakin Skywalker's redemptive death.

I might add King Arthur to the list.

I have been saying for some time that Harry's undoing is going to come at the hands of his best friend, Ron. (Think Lancelot.) Ron's increasing jealousy of Harry's fame and especially his money is going to get the best of him. It may even be unintentional but something Ron does (probably for money) is going to be Harry's ultimate undoing. In the end Ron will be a hero as he realizes the error of his ways. Or I could be wrong. :-)

I know I'll cry when (ok, if) Harry dies.
