CarpBrain said:Let's pick the following: Dark Sun, Planescape, Birthright, Al-Qadim, Spelljammer, and Mystara. This means that we can devote an average of 40-50 pages to each campaign setting, allowing us to cover how races, classes, skills and spells are different in each, while only including how stats may change. Each setting is only allowed to introduce (or stat up) two new races and classes. A section containing the requisite four to six prestige classes unique to the setting is appropriate, as well as a section discussing how running this setting is different than the core setting (ala the first section in Eberron).
I think you are seriously underestimating how many pages it would take to do what you are describing. Apart from a curtailed gazetter, what you have described is basically the full contents of a 300 page cs book.
If they did what you describe, I would probably buy it. OTOH, if they did a couple of campaign classics books a year, one setting per book, I would quite possibly buy several or all of them. Especially if the have a nice matching trade dress that triggers my collector instinct.
