Lupinlore:
  As I've said in another post, on a surface reading of
"either must kill the other for neither can live while the other
survives," we have three scenarios:
> 
> A) Harry kills Voldy and survives, saving the WW
> B) Harry kills Voldy and Voldy kills Harry, the WW survives
> C) Voldy kills Harry and survives, the WW is destroyed
> 
> Note, there IS no scenario by which the WW can be destroyed 
and Harry survives.  

Pippin:
Sure there is: Harry survives and destroys the wizarding world.
In fact, I suspect he will be offered just this choice, and it's 
foreclosed to Dumbledore so that Harry will have to decide it.
