I want to friendly point out that you might not be the majority of the players (I don't know if the majority uses pre-made adventures or not).
Oh, I'm well aware that I'm in the minority in many ways. However, there was at least one poll (and I'd love to link, but it was so long ago that I think it was TSR that ran it) that indicated something like 80% of the people (an overwhelming majority) bought Dungeon magazine to read, not to play. At 64 pages and 3-5 adventures for $5, Dungeon was a much better bargain than what you're suggesting.
You might not have a need for the format personally, but I want to point out that they might have observed that Paizo is selling adventures and making money out of it and are trying to repeat their success with their own spin (D&D Encounters).
I'm not sure I've ever seen a breakdown of Paizo's income stream separated into Adventure Paths, stand-alone adventures, setting accessories, setting hardcovers, and rule books. The adventure path modules offer more than just a mini-gazetteer and an adventure each issue, but I'll admit they still don't really tweak my interest. Kingmaker maybe.
Anyways, I suspect we're both in minorities. You think bundling adventures & setting material is "pretty smart"; I don't. Ultimately, neither of our opinions matter much.
I will say this. I think cloning Paizo's strategy is a very bad idea for WotC. WotC has a lot more intellectual property to leverage than Paizo, and ultimately, a different market. D&D has market penetration and awareness that Pathfinder only dreams of. WotC can certainly learn from Paizo, but outright copying? Good way to be #2.
