What exactly is AF2 gear from

[Zumi]

They said the mythology gear isn't af2 in the live letter, but there is a new set they are calling AF2. Does this come from Crystal Tower or something completely different?

[Naberrie]

We have no idea. They didn't say. At least not in either translation that I read.

[EmSix]

It's likely the next Tomestone set, since we've already seen the Crystal Tower sets in a previous letter.

[Lisotte]

I'm pretty sure it can't be crystal tower gear because that will be dropping ilvl 80 gear, while the current relic myth gear (which is a simple recolouration of the AF gear) is ilvl 90. Could be from higher coil, or maybe from pvp?

[Pellegri]

You can expect nothing less than the next tomestone set if they follow the progression line of justice/valor they have set in place. The little allagan they showed will be the new gear in the next set of turns in coil, while this will be from tomestones. They already confirmed 2.2 on this, why add a new tier of myth in 2.1 when there is no higher level content until 2.2?

[Iskander]

seeing as they weren't supposed to show the af2 gear yet, but that one man started showing accidently (according to translation), you probably won't see them for a while.

AF/AF0 = Job Quest Reward (first set)
AF1 = Allagan Tomestones of Mythology purchase (second set)
AF2 = Allagan Scrolls* (third set)

af2 wil most likely be on a new token style system

example: endgame content will at random reward group members upon completion (one per completion randomly to one group member - like house parts currently drop from HM and BC - a "scroll" or part of armor in token form, "Helm Scroll" would then be handed in to the npc in mor dhona for the helm of your choice)

Af2 in XI is the relic gear droped from dynamis
Here the mythology gear is the af2 but idk why they say it isnt
Af3 in xi is the empyreal gear
Here idk what they gonna call it

From the live letter translation this is all I could find:

y; AF2
w; That’s gorgeous
y; This one is 2.2
y; Oh crap I said it

So we only know that AF2 is coming in 2.2. possibly 6 months from now.

[Nils1986]

lol that fake leak.

So AF2 will be ilvl 100, possibly 110? I just hope they don't enter the WoW vicious circle (when you get +50% hp after every new set), it would ruin everything...
