I hope for a Pathfinder 2.0. The underlying rules system it is based on has critical flaws in it and it has not held up well when critically examined compared to modern roleplaying systems. It's 15 years old, and it is really showing its age. We've had amazing innovations in RPG design the past decade during a rebirth of roleplaying games. And PF benefited very little from this.
Hopefully Unchained helps a lot, at least for me.
This. Pathfinder really could use a rules update. Sure its a great game, but there are lots of places where the warts are well known and could use some base level modification.
There is a third possibility. Paizo could start releasing material for Pathfinder that is also 5E-compatible. Like the APs. It would only grow the potential audience for their products.
While anything can happen, I don't see that happening, for good reasons.
1) mastering 2 systems at once is not easy.
2) they would make PFRPG subject to the whims to another company (even if only in a minor way). That can really play havoc with operating capital.
3) they'd have to do a whole lot of 5e system work to make the APs work. They won't be able have alchemists, inquisitors, oracles (just to name a few classes), any monster from B2-4, any NPC from the NPC or Monster Codexes, anything but core book races, and much more in any adventure path until they catch 5e up to where they are.
that's just off the top of my head.
