Taken from the latest PoL article:
"In closing, I'd like to mention a succulent piece of gossip I recently caught wind of, kupo. Rumor has it that "Mog Tablets"—ancient treasures long dismissed to have been merely moogle myth—have reemerged after millennia in evanescence! Some say that the soul of the great moogle king, Kupofried—may he rest in peace—well pleased with the valorous display of adventurers, brought these magical artifacts back from the far reaches of living memory, kupo.
Only the Goddess knows what the appearance of these tablets heralds, but we magically attuned moogles are quietly confident that something stupendously special is brewing! We won't neglect to keep you up to date on the latest regarding these tablets, so stay tuned, keep that blade well-honed, and be ever ready for action, kupo!"
It seems pretty obvious, with the mention of the Moogle 'Kupofried', that the Kupofried's Ring will be obtained in some way during the upcoming Adventurer Appreciation Campaign (almost everyone probably suspected it). Does anyone else think it seems to good to be true that we might be able to get both the Anniversary Ring and the Kupofried's Ring? I do, lol. I have a feeling there's gonna be an event that you do to 'upgrade' your Anniversary Ring (unused).
