Someone I game with. I don't know where he heard it.
Sorry, then. It sounds like you and your gaming buddy are the victims of rumor mill churn. A quick Google search shows nothing regarding plans for a brand new setting.
I think it would be fun if there was a setting that took place before tge dawn of civilization, when aboleths ruled over humanity, and dragons ruled over dinosaur-riding lizardfolk, etc. etc. Kind of like a combo of Barsoom and Darksun with Far Realm overlords.
