no... I do not think so. with no OGL PF wouldn't exsist at all.
Actually, I'm not sure that's true. When the Dragon license ended, Paizo had to do something - it was that or fold the company. And with the d20 license also ending, any option of continuing to support D&D was also a no-no. So, although Pathfinder wouldn't exist in it's current form, it's likely they'd have produced something.
And it would have been a success. Paizo had two enormous advantages over everyone else in the market (WotC excluded) - access to the database of ~50k Dragon subscribers, and huge goodwill built up from their 5 years of running the magazines. This wasn't just some random startup; it was a company that many of their customers wanted to succeed.
The big question, of course, is how much of a success. After all, 'success' in the field of RPGs means selling a few thousand copies of your core rulebook and then maybe a few supplements. So, would our non-OGL Pathfinder have been a success on a par with DCC? With Shadowrun? Or, indeed, would it still have supplanted D&D 4e as the #1 RPG? (It's highly likely it wouldn't have been as huge as it is now, but then WotC made enough other mistakes with 4e that their success is really not assured even without the OGL-Pathfinder out there.)
