Well, judging from history, I'd say no, people won't.
As was mentioned, the Pathfinder modules top out at 15th level. And they have what, a couple dozen AP's under their belt now? If people were going to get tired of lower level D&D modules, I'm thinking they would have done so by now.
Lisa Stevens and co have done interviews on this and a lot of what they do was shaped by how well issues of Dungeon magazine sold. Basically the later issues of an AP like Age of Worms or Savage Tide sold less than earlier ones and they had trouble with people contributing higher level adventures just like TSR did. Most gamers did not complete an AP either apparently.
It was also implied that a certain setting when put on the cover also sold less that other cover. That setting was implied to be Eberron, its why Golarion is their only setting they have done for Pathfinder.
