You left Nerath off this list, but I'd put it at close to 90%.
Nerath/Nentir Vale was left off because its an odd non-setting setting. Yes, it has a lot of proper nouns attached to it, but it really never had a consolidated source of information: no map, no real history, very sketchy info. (And yes, I know it was designed like that on purpose). Furthermore, it cannibalized a LOT of names and places from D&D history (Isle of Dread Tomb of Horrors, Pelor, Bane) which makes it even harder to establish as its own "thing". So I have a hard time really standing out as a "setting" strong and proud next to Faerun or Eberron because they'd have to fill in A LOT of gaps to make it anything more than an implied default. I actually put it up there with Elsir Vale or Thunder Rift; maybe some modules might use some of those names in them, but I seriously doubt they are going to go through the hassle of filling in the blanks when even Greyhawk and Mystara already have maps and scores of sourcebooks to mine through.
