I'm not paying $50 so I can answer a forum question to your satisfaction. I will happily read the book if it is provided to me, but otherwise I am confident what I know of it is enough to make a call for me. I am also an experienced DM, so until I hear otherwise I feel that enough to be allowed to participate. It sounds like a great book for DMs in large part. I have bastion systems and lists of magic items that work for me, so the actual game content the book holds (so far as I know) is not especially useful to me.
