The Diomen guys, that much I know.
The Twin Crowns people seem to have moved toward LARPing. I don't know if they count or not.
It was just in the EN news - maybe a week ago - that Otherworld Creations will be putting out regional sourcebooks for Diomin via RPGNOW. They are also working on the Solid! blaxploitation d20 game.
The Twin Crowns folks put out "Streets of Silver" and "Spellbound" recently. Larry Fitz was also just asking people on this board what they would think of a book on economics for d20.

Were there some other press releases that aren't on the news sections of their web sites about them giving up?
