I'm going to say this with 100% assurance and certainty. WoTc will never ever outdo Piazo when it comes to support material.
In all fairness, they don't have to.
I've run AD&D adventures in Pathfinder , and I would have converted over 4th edition adventures had I believed them to be worth the effort. If the game is better than what I'm playing now and there's enough supplementary material to interest me, then I would make the switch and incorporate Paizo's stuff into the new game. But if it's just some rules I like and nothing built around it, I probably won't put the effort into making a change.
Realistically, the either/or outlook doesn't make a lot of sense. Even if D&D is a boffo smash hit, it's not like Paizo is suddenly going to stop producing quality stuff. Especially since the new edition seems to be more compatible with Pathfinder than 4th edition was, I see no reason why somebody would have to choose between the two companies instead of getting the best of what both have to offer.
