You forgot Gamma World but then it is not a D&D setting. But just so you know, it is not just about money when it comes to outsourcing IP brand. They want to make sure the integrity and the quality of the brand is maintained. After all, you don't want someone to have the license to Spelljammer and turn it into a Flesh Gordon/Barbarella erotic-type game for adult gamers only.Gez said:Ravenloft was the first, and the last licensed setting. Wizards came to the realization they could, and thus should, have made a more lucrative deal out of this.
Look at Dragonlance. The campaign setting is published by Wizards. Sovereign Press paid the cost of writing the stuff, SovPress also pay for supporting the line through sourcebooks; and Wizards reap the benefits of the sales of the best-selling book in the line.
Financially, it's a very harsh deal. I doubt you would find more third-parties willing to strike such a raw deal -- especially for a not-that-popular setting such as SpellJammer.
