Books 6 & 7 - no longer school stories?

Book 5 took the action outside Hogwarts for big sections of the 
story: Grimauld place, St. Mungo's, the MoM. This pushing out from 
the Hogwarts "home base" had started in GoF, but not nearly to the 
same extent.  I'm wondering if it's going to be impossible for 
Rowling to really contain the story at Hogwarts anymore, and if 
we'll be seeing the main characters moving outside the school for a 
lot of the action in the remaining two books.  In a way, this would 
make sense, as one of the storylines is about how the Voldemort 
threat is breaking out into the wider wizarding world, and even 
further into the muggle world (though that isn't as convincingly 
presented).  I don't see how Harry can remain at the centre of the 
story if he's stuck at Hogwarts all the time; despite the MANY pages 
devoted to Umbridge's nastiness and the burdens of exam schedules, 
not much of importance actually happened AT Hogwarts in Book 5.  Is 
Rowling going to have to invent one pretext after another for Harry 
to escape in order to fight Voldemort somewhere else?
