I also saddened by the fact that only two more books will be published into the Harry Potter series. However, I have also been keeping up with Jo Rowling's website and it's said that the next two books will answer all question about Harry, the furture and the past (Sirius, Lily and James) therefore there won't be anything left to write about... assumably. Yet, what I thought would be a good idea is if Jo Rowling herself published a resource book about stories that didn't make it into the final draft, where her inspriation came from ect. I would diffently by it. So, there are my two cents.
