I make no claims on what others can and cannot consider "success". You make your own determination. However, I wouldn't fault someone for feeling that until Paizo cuts it chops on something entirely new, their own, then they aren't quite there yet.
I'd make an analogy to an author who writes only "shared world" stories, or only works with public domain worlds. They may be good writers, but until they do something uniquely their own, they're still not quite top-notch.
Just not seeing how this is a requirement for success? They have to make a system, just to make a system, regardless of whether it is necessary or needed in order to be considered successful by some? IMO, making the decision on whether this is necessary or not is the real key to success... perhaps WotC couldn't make the OGL work for them... but if Paizo can, I think that speaks volumes about their success.
As far as making something that is their own... they do that with every adventure path they put out.
I also disagree with the shared world analogy, if anything Paizo is using the foundation of the OGL and definitely building their own world, rules, adventures, etc. around it.
I think, eventually, they'll need to acknowledge and jump it, or stumble and never be a major player in the race again. Their starting situation was unique, but from this point on they are subject to the same market forces as every other game publisher out there.
Eventually, the market will be saturated with Pathfinder materials. That's the reality of the niche. They will not be able to sit on 3e's laurels forever if they want to maintain their market position and size as a company.
Are they really sitting on 3e's laurels. Again, I would say it takes more business savy to come up with the products and process to revitalize a system that the largest rpg company in the biz has procalimed "dead" and is actively competing against... than you are giving them credit for.
