Personally I'm not that bothered, I'll read it. A few days after the release, as my brother [who has them all] will lock himself in his room and read it quickly.
I also loved the news article I read about JK crying as she came to the last few chapters, boo fucking hoo, feed the crack habit another way.
However, I bet she'll milk the enterprise by making a shitload of other stories, Voldemort - The early years and shit like that. I still think my ending is the best ever.
