The body piece in the picture and the current AF/Mythology gear is completely different. The elbow pads and the waist section are more flamboyant not to mention an actual tail component is showing.
Or they're going to continue with the myth system where(like other mmos) when a new higher tier raid comes out they make a new higher tier of badge/point gear you can buy along with it. The af2 they showed will(99% sure) follow that formula and will be for myth or a new tomestone, they are not remodeling the current myth gear, they are adding an entirely new set to go along with the higher tier of coil in 2.2.
They already confirmed af2 to be for 2.2 though, which is after Crystal Tower starts with it's first wing. 2.2 will be a new set in Coil, which they've already shown new allagan to go along with it. Af2 will either be new myth/currency items or it will be token drops, which if it were token drops they would have started with tokens for the first tier also(which they didn't).
It's extremely common in bigger name mmos to have tiers of content with patches and when a higher tier comes out so too does a higher tier of currency gear that can be bought off a vendor. If anyone is hoping for this to wind up being anything like 11 or 1.0 then that thought can be gotten rid of when it's clear as day how they want gear progression to be in this even with the minimal amount of content currently in. Nothing gets people subbed the longest like a currency grind that is on a weekly timer, people want that better gear and companies know a weekly timer will keep people logging in week after week if for nothing more than to cap for the week. With the current endgame how it is if there wasn't a cap then what reason would there be to login past having all the myth gear on your character? No reason to do coil when the loot is the same ilvl, no reason to do dungeons when you already have the best gear, no reason to login when you've literally beaten the game and have the best of the best items.
