Hello All,
I have a theory as to how Harry Potter will end, or at least how Harry
will kill Voldemort. I found a clue, after reading page Pg 743 (in the
UK edition of Order of the Phoenix) for about the third time... So
here goes:
 The room in the Department of Mysteries that is locked at all times
contains Love.(Dumbledore explains this to Harry - " 'There is a room
in the Department of Mysteries, that is kept locked at all times. It
contains a force that is once more wonderful and more terrible than
death... It is the power in that room that you possess in such
quantities and which Voldemort has not at all. That power took you to
save Sirius tonight. That power also saved you from posession by
Voldemort, becuase he could not bear to reside in a body so full of
the force he detests..." Voldemort detests love. 
And I firmly believe that the room Harry tried to open with the knife
that Sirius gave him, (when the blade melted - please refer to page
684 of the UK edition) is that room! I'm sure of it!
I think I know how it will all end. I think that Harry will have to
somehow trick or take Voldemort into that room at the Department of
Mysteries, and that the force of the love in that room will kill
Voldemort.  
Or if it doesn't exactly happen in the way I have outlined above, it
will definately have something to do with that room and/or love.

So, what does everyone think of my theory? I'm thinking of naming it
'All you need is Love' ;-)
