I voted for Dragonlance, not because it is what I want, but what I think it willl be.
Although Red Steel has been proposed and it would be interesting if that was the case. I dont think I would mind to much if WotC was intent on pillaging the Vaults for some interesting, unusual settings.
We have been told that the setting has an "a" in the name, so it's not going to be Red Steel.
