A Harry Potter Discussion- What do you think???

From what I have read of the last book ("The Deathly Hallows"), I think that Harry (and most likely Ron and Hermione) will not be returning to Hogwarts. Harry said at the end of "The Halfblood Prince" that he would not be going back. Yet, I think that at some point the three of them will need to take their final exams in order to become full-fledged magicians and determine what their magical futures will be, unless that would not be necessary if they (or Harry in particular) are able to rid the magical world of Voldemort (although I tend to think that he is immortal to some degree; I doubt that he will be killed in total finality). As for Quidditch, it may have run its course for Harry since he is unlikely to become a professional Quidditch player. I really do not have a clue about RAB. I do love the Harry Potter books and think that J. K. Rowling is about the cleverest writer ever! I can not wait for the next (and I really do hope not the last) book to be released on July 21st and want to purchase it immediately before I hear how it ends!!
