Like I don't really quite got the whole Alvis/A split and what drove Alvis so genocidal, or what happened to like half the cast of XB1/2, or what exactly Shulk, Rex, and A are doing in the ending. I never understood any of the Fog Beast stuff in Future Connected and still don't understand why they're running around in Aionios.

Also I guess the worlds merge again in the end but I wonder how it works exactly. Like do people born on Aionios still exist or what? Also did they actually try and tie the story from fucking Xenoblade X into this?

Also apparently I need to play Xenosaga finally.

And yeah, the lore implications of all of this are nuts; hell, if I have the metaphysics, right, not even A, who I was fully expecting to end up being permadead outside of Aionios, might end up being?

I don't know that I understand the mechanics really, but I'm guessing they'd bring A because how could you not? A rules.

Tbh the more think about it the more I really hope the specific implication of the radio scene isn't that this is all just XBX prequel i.e. the worlds remerge and then get owned by the Ganglion from X. That would kinda bum me out tbh, but its hard not to notice the similarity of the city in that scene to like New Los Angeles. Though if that is the case, it would maybe give Z an actual sympathetic to some degree motive to perpetuate the Endless Now if he somehow knew that the Ganglion were coming down the line otherwise.

I did like this crackpot theory I saw online that perhaps the alien world from X is actually the remerged Earth somehow (And it would sorta kind of explain weirdness in that game's own ending) but I don't think I'm ready to commit to that yet.

My knowledge of X is very minimal, so I don't really have any takes on this; my gut response is probably not that, especially since I've seen some people say that the namedrops in the radio were Xenosaga, not Xenoblade X

Yep, these are references to Xenosaga Episode III; Dmitri Yuriev, who is mentioned on the radio, is the main antagonist of that game. MONOLITHSOFT had to ask permission from BANDAI NAMCO* to use the name and also the logo that can be seen on the radio. I don't see a connection with Xenoblade X yet.

References to Xenosaga are nothing new in Xenoblade:

• KOS-MOS and T-elos are heavily based on KOS-MOS and T-elos from Xenosaga;
• Pyra’s, Mythra’s and Malos’s Core Crystals from Xenoblade 2, as well as Alvis’s necklace in Xenoblade Definitive Edition and A’s earing in this DLC, all them are heavily inspired by the Zohar – there’s an eponymous object in Xenogears too.

In the post-credits scene, something is seen falling from the universe towards the new Aionios. It is very similar to the ending of Xenosaga Episode III when KOS-MOS drifts to Lost Jerusalem (Earth).

Xenosaga was not finished properly, due the poor sales the project was canceled. I don’t know what they're really planning with all this, but the possobility of a Xenosaga remake isn’t out of the question.

The Project Exodus stuff that the radio mentions is straight out of Xenoblade X, which is big part of entire premise of that game. It seems likely to me that they're melding Xenoblade 1-3, X, and Saga trilogy into some kind of super narrative even if some details along the way get changed a la Definitive Edition changes to align Xenoblade 1 with XB2's reveals. It might also be something more akin to Turn A Gundam's "Correct Century" timeline that has different shows fitting together even if the specifics don't quite make sense.

The "Philadelphia class ships" they mention are apparently a Xenogears thing I forgot about, but because legal headaches involved I doubt we'll get many explicit connections to that.
