Frankly, I won't shed a tear once new "official" Greyhawk supplements stop coming out. The less stuff that's released, the less they'll continue to ruin my beloved Grehawk.
I know that Erik is a true fan of the milieu, but he is naturally beholden to the corporate masters, and businessmen make piss-poor hobbyists. Even his kindly influence couldn't halt the decline.
If Greyhawk is ever revived, let it be done by a group of true fans of the setting, who are hobbyists themselves, who won't try to approach it with some agenda of "tearing it all down to start over", as was done with FtA, or to try to change its nature to wring more sheckles out of hapless players on hardcover books that should be released as softcovers for half the cost. Let it be revived by those who understand the unique nature of Greyhawk, and who are willing to embrace that nature. And let it be revived by people who don't feel so personally threatened by Gygax and Kuntz that they are creatively locked out of their own creation.
Let it be revived for the right reasons. By people who genuinely love and believe in the setting, rather than someone looking for a quick buck and who sees Greyhawk as the means to make said buck.
