Yeah, George insisting in the AOTC commentary that everything around Sifo-Dyas (and Kamino being missing in the archives) is going to be explained in the next movie is quite funny in retrospect, since it would actually be 12 years before it was addressed at all, by something Lucas was involved in at least. Something something nO pLaN.

I kind of feel it’d’ve been better if he’d just left it as Sido-Dyas to keep the plot of the prequel trilogy more self-contained. That’s something you could definitely do in a fanedit with a little audio tweaking, or by dubbing and subtitling the Kaminoans, if you weren’t concerned with maintaining continuity with TCW.
