There seems to be a recent trend in RPGs for a return to rules lighter games. We've seem the rise in popularity of FATE, Cortex +, Savage Worlds, Dungeon World, Numernera, IKRPG, and others. Other games in development are turning from complexity to easier to digest rules. Companies like Crafty Games who traditionally have made quite dense games rules wise is apparently dialing down the crunch quite a bit for Spycraft 3rd, and of course WotC is making D&D next a lighter set of rules first with complexity to be added later.
Heck, my friend who LOVES crunch in rpgs is now looking for lighter games and got fatigued by Shadowrun 5th very quickly
One wonders if this trend will affect Pathfinder
