Is that a PF2 jab? The only reason I can think of to expect an increase in the number of fans is if they flee some other game. Otherwise I'd expect a no-longer supported game to stabilize somewhere and slowly bleed out players as people eventually move on.

I do sometimes think about what I would do differently if I was to try to do the PF treatment to 4e. Would it be better to mostly keep the same game and polish the edges or would it be better to try to take some bigger risks?
