I'd like to see a Pathfinder Module that would be designed to be a possible follow-up to one of the existing (or future) adventure paths as well as a stand-alone.
I would think it would have more sales appeal than a high-level module out of the blue since it would tie in with Paizo's flagship product: the adventure paths.
I'm sure if I asked my players whether they'd like to whip out their high-level PCs from Rise of the Runelords and go through another adventure, I'd get a resounding yes.
Just a thought.
