As I have my fingers (or puppet strings
) in almost all the D&D stuff here, I can confirm that there is not many openings for D&D. Acrem's game is seeking a player or two, but it is homebrew 3.5ed and not a regular game IIRC.
I have heard talk and inquiries of 4th edition, but never seen a game even try to get off the ground.
But other than myself DMing PF after starting to switch from 3.5ed, we have not had any DMs last for running those games. Storm disappeared again and no news on his return. The rest of our D&D DMs in the Guild are sticking with 3.5ed.
I have been contemplating putting PF into the Guild, but that won't make more games for people, just convert existing groups.
