The developers of Xenogears split from Square after the FF7 was made and joined Namco to produce the Xenosaga series. I read that apparently Xenosaga is the prequel to Xenogears and there are "supposedly" 5 episodes leading up to the time of Xenogears. The Xenosaga anime is episode 1, which was when they discovered Zohar and the wave existence 15000 years prior to the events in Xenogears. Episode 3 or 4 is about the Zeboim civilization seen in Emeralda's side quest (which would FUCKING ROCK MY WORLD). It's all speculation as to how closely related Xenogears and Xenosaga really are, because despite all the similarities, there is no KOS-MOS reference anywhere in Xenogears.
well, i guess this is all off-topic as this isn't a Final Fantasy at all... but then again I am much to lazy to create a separate Xeno topic.

i was pretty sure that at the end of Xenogears they say, at the very end of the credits:
XENOGEARS EPISODE V

So there would only be 4 actual episodes before the events of Xenogears. I also always believed these 4 previous chapters would revolve around the characters known as Elly and Fei.

Episode I: Elly and Abel. Also the beginning of the Gazel ministry.
Episode II: Elly and Kim: the rise and fall of Zeboim
Episode III: ??? This one I simply can't remember. Was there a third reincarnation of the two before...
Episode IV: Elly (Sophia) and Lacan. Nissan, Krelian, Grahf, a painting.

Also, i gathered this from the Gamefaqs; message boards (yes i know that people there have a dubious reputation, but this time I feel they are correct) :

Xenogears was made before Xenosaga,obviously as they kind of stopped making PSX games after PS2 came out and Xenogears is a PSX game.
Xenogears is a part of the Perfect Works and is episode 5 of the series,so basically Xenosaga ep.1 and 2 (3 on it's way) are before Xenogears.
Since Squaresoft (Square-Enix now) owns the rights to Xenogears it was stated by Monolith that Xenogears and Xenosaga have nothing to do with each other and are 2 separate story's.
I guess we'll have to wait and see what happens in the future,if they ever decide to make part 4 as there's a rumor going on that Xenosaga ep.3 might be the last in series.

Xenogears is not part of the Xenosaga storyline yet. They are separate story lines. In terms of what were created first. It was Xenogears the the move to Namco/Monolith Soft to create Xenosaga.

So it seems to me that since the development group that made Xenogears broke up, and the people that made Xenosaga have no rights over the storyline of Xenogears (including all the pertinent flashbacks that would make up key parts of earlier Episodes), both a remake of this game and any actual sequels/prequels seem unlikely. Fuck those money grubbing motherfuckers.
