Well Cliffe said that Amazon´s info is out of date. And if one of the people who worked on the book says it´s going to be hardcover, it´ll probably be hardcover.
I ordered it from amazon.ca, it said softcover and when I emailed to confirm it was softcover, they insisted that it was, BUT
when it arrived, it was hardcover with a paper jacket. It's a good book, not enough commentary but the visuals make up for it
It's basically the coffee-table book to end all coffee-table books.
