I know it might be old news but it's a bit sad that Frank Herbert died before he was able to conclude the Dune series. I know his son went on to finish the series but there's no real information to show that it was based on Herbert's actual notes.
Just sad that the 6th book ends on a partial cliffhanger and we'll never know what he truly intended the 7th book to entail.
@DoggFacedGamer I think he would've gone much weirder than the greatest-hits package Brian concluded the story with.

@horacemajeur I don't doubt that, the series really started down the weird path with the 5th book.
