I read in the past that original Frank Herbert notes were found in a safe deposit box. These spelled out the prequels and the final book to the series. From what I read they(Brian/Kevin) were going to use only what Frank had left behind. So in essence these books should be looked at more like rough drafts from Frank Herbert than complete books from Brian/Kevin. I can't wait for the mini-series or the final book. I alwasy wondered if it was supposed to end with Chapterhouse Dune.
