Those seeking the reality of the situation can read my older essay (longish, over 5,000 words) published many years ago:

Pay particular attention to its ending and to WotC's non-reaction to the Greyhawk Market Plan that I submitted to them with Gary's approval (In summary, we heard
Crickets)
Later... 2004 Erik Mona championed a Greyhawk resurgence at Paizo when they had the licensed magazines. Thus was produced Maure Castle, authored by myself, Erik and James Jacobs and with some input from Gary and the republication of his Sword and Sorcery in Wargaming article from 1975 (that details the adventure of Mordenkainen and crew into an adjunct level to my Castle El Raja Key that was the precursor to Mordenkainen;s Fantastic Adventure that I expanded upon and wrote in 1984)).
As many are aware Maure Castle (Dungeon #112) was a resounding hit and sold out even with hundreds of extra copies printed (it remains to date the best selling issue of Dungeon). It also won a Golden ENnnie (Thanks ENWorlers!!); but after two more installments by me and with more on the horizon (with Erik's envisioned compilation of all installments into a HB book) WotC pulled the magazine licensing from Paizo for their own online, in-house initiative. They had a hit with Maure Castle, but never approached me about continuing it.
Next, about two years ago, I wrote Mike Mearls about rebooting Greyhawk. My response was the same Gary and I received in 1997--crickets.
Portents are often the same as facts...
