If they got the license they'd probably have to give wotc a portion of their sales. Better off sticking to the SRD and homebrewing in the gaps.
You are right. Lets be real, Wotc has made a total of zero interesting settings. Solasta is a bit interesting. I would't put in the same tier of Dark Sun, but Solasta is far more interesting than sword coast.
"but what about eberron" "Eberron was created by author and game designer Keith Baker as the winning entry for Wizards of the Coast's Fantasy Setting Search, a competition run in 2002 to establish a new setting for the D&D game. Eberron was chosen from more than 11,000 entries, and was officially released with the publication of the Eberron Campaign Setting hardback book in June 2004" from wikipedia
BTW : DDO is based on Eberron and a decent mmo. Would be cool if we get more video games set there.
