Right now circulation of the adventure paths in general is still increasing, and last I had heard the rate of increase was accelerating - there may be a 'diminishing returns' in the future, but not yet. (Though I do gather that there was a jump 'n' slump because of Kingmaker - which sold extremely well, the next path did better than the one before Kingmaker, but not as well as Kingmaker. Folks wanted to take their shovels and play in the sandbox....I suspect Paizo is already seeing diminishing returns on their adventure paths. Although I am certain there are people who blast through each chapter when they come out, many more, I suspect, are getting further and further behind and don't have the incentive to keep buying more paths at this time, to say nothing of all the standalone adventures. The question is how bad the drop-off is and how fast it accelerates. (Obviously, there are a lot of people who buy them just to read them or as simple collectors, and that helps cushion the blow.)
At some point, they will want to change their model.

D&D on the other hand is not doing that well locally, so their point of diminishing returns has possibly been reached, again, at least locally - especially factoring in their now slower release schedule. I actually doubt that Paizo will be changing their model all that soon, whereas WotC is currently changing theirs.
Pathfinder is not relying as much on an 'everything is core, everything must sell!' as WotC was. They do not try to market every product at the same level, which I believe WotC was trying to do for a while, or something close.
And, for the record, WotC changing their model is not a bad thing - they were saturating their market, now they are moving to remedy that. Returns were high, now they are going back down. Returns are the Devil. The Devil, I say!!!
