What are you talking about? There’s the whole conflicting histories (and names) of the Zohar/Conduit that can’t just be hand waved away. In Xenosaga it was Grimoire Verum who lead the experiment with the Zohar that resulted in the large scale matter shift that expanded over Earth, forcing humanity to flee the planet, and then Wilhelm had to step in to contain it from spreading beyond Earth. In Xenoblade, however, it was Klaus who was responsible for the Conduit experiment, and this one was instantaneous in its destruction of Earth (and creation of the world of the Bionis and Mechonis), not slowly making the Earth disappear and giving humanity time to escape as was the case in Xenosaga. Plus I’m pretty sure the Zohar experiment in Xenosaga is supposed to take place fairly later in the timeline than when the Conduit experiment happens in Xenoblade, though I’m not 100% certain about that. Regardless, it’s absolutely clear that these events contradict each other and simply can’t be one and the same. It’s far easier to fit XCX into the existing Xenoblade Earth history—Future Redeemed shows us that Project Exodus was a thing that had already started, after all, with some arks having already been launched and others prepared, including what is presumably the White Whale, and what we, the audience, saw of the Earth being blown up could easily just be Klaus’s experiment happening; it wouldn’t be too much different from the retcons they made in XC2—but, again, that’s not the only option, and I personally lean towards XCX Earth being a universal reset occurring after the universe of Klaus’s Earth, à la Eternal Recurrence, though there are plenty of possibilities. Point is, even if you were to make XCX Earth and Klaus’s Earth be one and the same, it would still require less retcons than making Xenosaga fit. Meanwhile we know for certain that XCX is supposed to connect, so to assume Future Redeemed is somehow setting up for a big Xenosaga connection more so than XCX just doesn’t make much sense at all. That’s not to say that I think the Xenosaga references have no significance, but I don’t believe that it’s hinting at this grand, direct connecting of the two series as many people seem to think. And no, it’s not difficult at all to read FR’s ending as something other than KOS-MOS. They’re not even that similar. If it was more 1:1, then sure, maybe, but it’s quite a bit different and there’s no good reason to assume that that blue dot is supposed to specifically be KOS-MOS rather than something else. Besides, KOS-MOS already has a role in the Xenoblade universe in XC2…
