I think what would be awesome as future hardcovers are Pathfinder RPG books with real-world cultures as themes for a generic fantasy/Golarion version of them.
Such as an Ultimate Far East, detailing Tian Xia as part of the book and the rest a bunch of material for fantasy Far Eastern material such as archetypes, spells, expanded rules, NINJAS, and so on.
Others could be Ancient Americas, Egypt and such

Well, it's not going to help if you're playing PFS, but Heroes of the Jade Oath is a thing. Publishers like Legendary Games have also put out a lot of culture-themed supplements that are perfect for home games.
