This was already explained. Everybody is getting new AF type gear. The i90 gear people have been calling AF2 isnt actually AF2. What it should be called? AF+1, AF1.5? IDK and IDC. The new stuff is AF2, according to the devs, and it seems like it will come from future content in patch 2.2 (so a good 3-6 months down the line, I'd guess). They showed off MNK, DRG, SMN, BRD, and I think one or two others. Its iconic job gear, but not just a cheap palette swap like the i90 AF.
