My checklist jibes with Spookythecat's calculations. Assuming a one-per-month release schedule, the 200th MMW will come out in paperback in early September of 2025--precisely 12 years and 3 months after this month's F.F. Vol. 9 came out. And if the HCs are monthly, too, which I think they are, then that lag time-frame can't change.

Now, if TPTB decide to boost the paperback frequency, as was done with the HCs for a time, then the gap can be narrowed. I really hope they do this, at least for a time, but I'm not counting on it. Besides, I'm patient ... I can wait for paperback. It's not like I don't have any other hobbies to spend my money on.
