The 5e version actually has quite a bit that isn't in the Pathfinder/13th Age version of the book. Stats for khopeshes, mace- axes, warspears, and chakrams, an extra Gret Old One, and more. I guess that when they rorganized the material in the book (since this version is for a single system, they didn't have to push all game rule information to he appendix), it freed up a lot of space for them to fill. We re also going to get a Players Companion and a GM Companion and a couple extra adventures on top of the conversions for the adventures included in the Pathfinder/13th Age round. The meat and potatoes of the setting are exactly the same, though, and there are a few editing errors - a typo or two, and extra period after a sentence, inconsistent use of terminology, using the term "subtype," which doesn't exist in 5e, etc. But overall I'm thrilled with the book and I adore the setting.
