It's interesting. As good as the licensing was for 3rd edition, it was part of the cocktail that created Paizo and Pathfinder (not the only factor, but one of them).
Given that they've clearly decided to shift their focus away from creating new players, and towards bringing back those that jumped ship, it would be a big surprise to me if they went with a very open license again.
I dunno, though. Anything's possible at this point.
This isn't wrong, but I wonder just how much of a factor the OGL was.
Paizo was created not to publish OGL materials, but to publish Dragon and Dungeon magazine; they switched their focus after the magazines were yanked away from them.
Likewise, they decided to go with Pathfinder as its own RPG largely because there was no word on the role of third-party companies in Fourth Edition for such a long time that Paizo simply had to go in another direction to remain financially solvent.
Had WotC handled the issues of the magazines better, and had a proper plan in place for third-party publishers in 4E from day one, then even with the OGL's existence they could very likely have brought Paizo on board with 4E.
