This was a discussion I had with my 13 and 16 year old daughters the other day so I thought it would be a discussion suitable for this board.
I say no because it would be major downer that would cause the movie company that produces the HP movies to lose a bundle on the next 3 movies as well hurt the DVD sales of the new movies( as well as the sales of the special complete package sets you know are sure to come after the last movie.)
So, unless JK has all the money she wants and didn't sign an agreement with the movie company agreeing not to kill off HP then I suspect ol' Harry lives on to fight another day after Voldemart is vanquished.
And I don't buy the argument that she kills Harry off just keep everybody else from using him in future books. Hell, how many times has Voldemart come back? Why would it be so hard to have the readers believe that , in a series based on total fantasy about witches and wizards, that even if HP were supposedly dead he couldn't be brought back in a manner acceptable to the fans?
Is there a dead pool on HP in Vegas? I'm thinking I may just want to lay a bundle on the side that says HP lives.
