well.... Your "real" primals are supposedly still coming. Although they've been 'coming' for 2 years now......

Yoshi in 2012:

The players will get together in their Free Companies [guilds] and they will fight Ifrit. If they defeat him, they will get the opportunity to summon him once. That Free Company will get to decide where and when to use him. Then Ifrit goes out to another place in the world for other people to go get him, so it’s like this competition between people in the world. This won’t be instanced, this will be public content, so anyone in the world can do it.” Until Ifrit is summoned, no other player group will be able to summon him. When Ifrit is actually brought into a fight it seems like nearly everyone in the server will know, because the skies will turn red. Then once the skies clear, you’ll know Ifrit is again available to defeat and acquire. “The whole world is involved in the summoning of these monsters.
