It's listed as paperback on the Wizards site, as well. How disappointing. It will look silly sitting on the shelf with all the hardcovers...
...which I guess is a stupid reason to be mad that it costs $15 less than it would have otherwise. I dunno how to feel about this, I guess!
I think a better question will be whether or not the Essentials' trade paperback size will become the norm. We know that Heroes of Shadow will be trade paperback, as will the Nentir Vale Gazetteer.Well based on the fact that the essentials line is soft cover,and things like the Dragonborn/Tiefling books and Hammerfast are soft cover...
My guess is they plan to do more of this type of book... so it won't look lonely for too long.
My game shelf is a mix of hard bound and softbound stuff anyway though.
I saw on Amazon the Darksun Creature Catalog is a soft cover book?
Did we know this already?
