Maybe you're right. Not to split hairs, but I thought the AV52 production continued into early 2018, or perhaps they were just still in stock then. On another note, I've tried all the iterations of these and I can attest that the latest one (the AO '50s) is the one I like the best. The neck and frets put it over the top, it feels super good to play. My only quibble is that I wish they had carried over the "bananacaster" or "Harper" blonde-ish finish on the AV52 "PV" series to the AO '50s instead of going back to the "pumpkincaster" dark butterscotch finish that looks like the AVRIs.
