Well... We might see more SF, since I doubt PF2e will be able to compete with 5e (and no matter what Paizo says, they will compete).
Then again, AFAIK, SF isn't very popular either... So Paizo is bound to lose a lot of busisness in the coming years. They probably won't shrink back to their pre-PF size, but my prediction is that after a short rise in sales when PF2 is released, Paizo will quickly be back to their current status of dwindling sales and popularity...
It doesn't help that they sanitized and censored their forums to the point where it's the echoest of echo chambers... They got woke... We know what happens next...
