We know AF in this game received during the level 50 Job Quests are named after the FFXI AF gear. The second recolor i90 is named after AF2 (relic armor) from FFXI, and the Esoteric AF set is named after the Empyrean armor (AF3) from FFXI (with slight differences to avoid confusion e.g., there was no Lancer class in XI, so AF3 for DRG was called Lancer's Mezail etc, while in XIV it's called Dragonlancer's Mezail to avoid confusion).
That said, we know that RDM's will likely be "Warlock's", and DRK's AF2 will be "Abyss" (it even has the purple elements that FFXI's DRK AF2 had). SAM might be Myochin but they are cloth based in XIV as opposed to armored in XI, so I doubt they'll be getting a Kabuto/Domaru, and likely instead get a Kimono or something as shown so far. Obviously XI didn't have Machinist or Astrologian, so those will likely have new names.
