I'm not saying this would work for WotC, or that it would be popular or liked by anybody but me. But this is what I would love.
2 adventure paths a year. Each set in a different setting. One is an old, classic setting, one is a new setting. Each takes characters up to about 20th level and are designed for 6months to a year's play. Most DMs will buy one a year.
Each AP has a shortish setting guide which introduces it and adds any specific character options. Not too long - you want to hand this to players and expect them to look at it.
Each setting/AP is visited once, then move on. There's Ravenloft, and Spelljammer, and Eberron, and all that cool stuff, plus a brand new setting each year. The new settings can be high fantasy, low fantasy, horror, magitech, steampunk, gritty, dinosaurs, ninjas, whatever.
The ones that are really popular? Revisit 'em with a second AP and another setting guide with more info.
