Recently, in Greek class, I saw a painting which showed what's-her-name dying in the arms of Achilies while releasing her soul. Which wouldn't have anythign to do with Potter but that the soul was drawn as a tiny ball-like thing with wings. WHICH brought me to the following crazy thought which would be awesome but probably won't happen idea about how JKR could end HBP:
In Stone, Harry is told to "catch the snitch or die trying"
The snitch looks like the Greek representation of a soul.
In Potterverse, souls are frequently taken out of bodies and put in other places.
Harry instead of catching the snitch SWALLOWS it and then, to put it mildly 'RELEASE
In further books, Harry is basically told he needs to KILL VOLDEMORT or DIE TRYING.
Harry has a preculiarly tenacious soul which refused to leave him when Voldy cast AK.
and an Attractive soul considering Dementors wanted it over the other juicy ones in the area in POA.
SO:
What if, instead of trying to release it by ordinary means, Harry tries to ANNEX it.
At which point his own soul rebels and releases Voldy's soul,
at which point Voldy's own is released into wherever it is in Potterverse that evil souls get to,
and Harry moves on in life completely free because everybody thinks he's dead because it looked like he lost his OWN soul.
TADA!
... no, I don't think so. The plot will have to remain in fanfic.
Or WILL it...
