I believe WotC actually really wanted Greyhawk to succeed. They've bent over backwards to put stuff out for it because they like it, and perhaps they've listened to the more shrill voices on the internet that led them to believe that the market in general wanted it.
BS.
Again, WHAT products? You can count THREE products through the 3.X run, 2 early and one late.....
They did NOT bend over backwards. At all. I keep hearing this myth that WotC did, but the reality is clear on the shelves...20+ books for each of the other two settings....and exactly ONE hardcover for GH.
PLease folks, stop with the nonsesne the WotC supported it. They didnt, at all. I have no idea if they wanted to kill it or its a conspirocy or whatever....but support was lacking. Thats easy to see.
