I've spent a lot of time talking to Peter Adkison (well, years ago anyway), and I can't think of better hands for the game to wind up in.
But a one-man show would collapse pretty quickly.
So the aforementioned Cabal of Chris Pramas, Sean K Reynolds, Monte Cook, Clark Peterson, and Gary Gygax as his "top men" sounds good to me.
And, to me at least, I don't think Gygax's position would necessarily be just a nod to posterity. I have just finished perusing "Canting Crew" and thik EGG still has a lot af gas in the tank.
