Will you have the willpower? (Will I?)

As we approach the July 21st release date of the final Harry Potter installment, something occurs to me: everyone seems to think that either Harry or Voldemort (or both) will die at the end. So once you've got the book in your hot little hands, will you instantly flip to the back and see how it ends, willpower be damned? Or will you, somehow, manage to make it through all 784 pages without so much as a peek?
