Wait... so the only way for the hobby to grow is if WotC grows?
No. The only way for the hobby to grow is to bring in new players (or bring back lapsed players).
My experience (and that may not be worth that much) is that WotC is making a much more concerted effort to attract new players than Paizo is. I'm not making a value statement of which is the better company, has the greatest staff, or the best products. I'm simply stating my opinion that WotC designed 4E with the intention of bringing in new players. Paizo has taken an old game, polished it up a bit, and has made it a beautiful luxury product for dedicated fans.
If I had to compare to video game systems, I would say that 4E is the Wii while Pathfinder is more like the PS3.
