If you mean the rotating GM thing, I just can't see that happening. I doubt Tom is about to tell anyone "Hey thanks for all your hard work over the years, but your era is done here is your replacement." Unless the current GM wants to roll with it I would think its dead in the water.
There are plenty of NPC characters. Rotation wouldn't have to mean "okay, you went from controlling all to controlling nothing", bur rather, "you used to control this bit, now control that bit".
I understand the fear of GMs going rogue, though.
