Iscah, honestly, it feels like you're doing a lot of Doomsaying right now. In theory, there is a possibility that the writing team will throw everything in the garbage and instead focus MSQ entirely on Hildibrand-style shenanigans. In theory, it's entirely plausible we'll get the Turali version of Ifrit that's actually very nice and gives ice cream to children. In theory, it's possible that CU3 decides there'll be no more MSQ going forward and we'll just get new raid content. It's not a 100% possibility, but it's not 0, either.

That's what that answer read to me as, at least. And it's not even the first time that Yoshi-P's given an answer that basically amounts to "I mean, this is open here if you want to write fanfic about it." Because they like to poke at player creativity, and the "multiverse theory" he's talking about is basically locked to two universes which were already "connected" back in ShB (and if anything, sounds to me more like "hey, if our writers want to write another short story about that timeline, or you guys want to write fanfic about it, who am I to stop you/them?"

In no way is he saying we're going to get travelers from the universe where Varis was a good father and Zenos is our best friend but for reals this time.
