Relaxed Intensity
If it splits you will see an uptick in Pathfinder2e. I already sense an uptick on Pathfinder2e coming anyway now that the full potential of the system is on display.
I doubt it. Those who feel disenfranchised are unlikely to find much solace in Pathfinder Second Edition. When it comes to a more socially conscious approach to lore and designing races/ancestries to be able to work well for pretty much any class Pathfinder Second Edition and 5e are following similar trendlines. I happen to prefer Paizo's solutions to those design problems, but I do not think most of the people who feel 5e is going in a different direction then they would like are going to find Paizo more receptive to their desires.
