Total non sequitur. I was around an about during the 2-3 change (it's how I found this site) and while memory is a fickle mistress, I don't recall their still being such a backdraft 20 months into 3E's life cycle.
There was no backdraft because it was time for a new edition. 2e had gone as far as it could go. There was a real threat that D&D would die with TSR. DRAGON Magazine and DUNGEON Magazine were forced into limbo.
WotC swooped in, bought TSR, and saved the game. Everyone assumed that they'd make D&D their own. Sure, some people worried about D&D becoming more like a CCG (including me), but those fears were quickly put to rest when 3e came out. WotC stayed true to the history of the game and built something that seemed extraordinary at the time.
It was new, it was different, yet it was still D&D! Plus, there came the OGL. That was an unexpected twist. It was a wildfire that caught on with the Internet crowd and 3PPs.
Thus, changing from 2e to 3e can hardly be compared to changing from 3e to 4e. (IMO.)
3e wasn't even close to death although it had grown a bit bloated. WotC simply wanted to distance themselves from the OGL. They wanted to regain control over D&D as a brand, and I don't blame them for making that decision.
They had to do it.
4e became about reinvention and it could be said to be revolutionary instead of evolutionary. Canon be damned! It had to change to bring in new gamers.
Our world is not the same as it was even 10 years ago. Technology continues to change our world and has now changed the way RPGs are played and perceived. An online model was a requirement to compete with WoW, XBOX, and the like.
Personally, I will always prefer 3e to 4e. (NOTE: Now, I also prefer BECMI to 1e/2e [rules not fluff].) Still, Dark Sun has brought me into the 4e fold; however, I will never be a 4e fanboy.
I'm too attached to the history of 2e and older editions.
WotC would have to put out Greyhawk (classic version), Mystara (plus Hollow World), Planescape (with the Great Wheel), and Spelljammer as "3 book" campaign settings in order to truly convert me, and if the interview with James Wyatt says anything, it says that those settings aren't likely to be redone (at all or in such a way).
IMO, Dragonlance will likely happen, but I think the next setting will be something completely new. Something revolutionary, perhaps?
Anyway, I'll stop ranting now.
Cheers!
