I don't know what it is, but I get the feeling that Wizards of the Coast are worried about Paizo and Pathfinder, but Paizo isn't worried about Wizards of the Coast. I've never really gotten the impression that Paizo is trying to pull customers away from D&D over to Pathfinder. It's like the company is so comfortable in their own skin that they just continue forward without a care in the world what Wizards does.
Now I could be wrong entirely, but that is the impression I am under.
