I would rather books about new classes and PCs.
About setting I advice Genefunk and Obsidian Apocalypse by LPJ, Lost Citadel and Freeport by Green Ronin. Kaidan by Rite Publishing. Iron Kingdoms by Privateer Press (I am awaiting the translation for this year).
Pugmire by Onyx Path and Humblewood have got potential to be kid-friendly multimedia franchises (toys, cartoons and other products), to be more popular than "My Little Pony". Hasbro should keep an eye to avoid these to be acquired before by a rival company, for example a videogame studio or a streaming service.
But there are too many after crowdfunding in Kickstarter there aren't news. I can't remember all.
Sirens: Battle of the Bards (by Apotheois studios) could be acquired by Disney, or Dreamworks, to produce a musical fantasy animate movie.
