Ok I may be a geek (computer, Scouting, wargames (table-top and computer) etc. ) but this is just silly, I admire single minded dedication to a topic of study and I really like Harry Potter books but come on folks - isn't worrying about the number of pages / chapters in a book grasping at straws. 'We can't find out anything else about the plot so we'll make the number of pages news?' The book will come out when it comes out.
