Those who have bought during what seemed to be the peak year for AF 15 back during summer of 2017 was it? Yes their sky is falling. Heck I'd be depressed and pissed off if I was one of those buyers during the course of the year.
Who knows when values start to pick up again. I have no clue, but hoping they will at some point. Like I've been saying before when we see AF 15 copies selling for much less than they did a year or so ago, it means most of the keys will follow suit, and it did. There are I'm sure some exceptions but overall it's been down.
