Xenosaga is not an episodic game exactly. Episode II will be the last you see of KOSMOS, Jr and Shion. The next game will be set several thousand years ofter those events (Xenogears was Episode 5 and IMO if Monolith (in Square back then) didn´t a big fat "Episode V" thing at the end, we wouldn´t have found out), and the rest of the games will be similar to it.
Actually, Takahashi is not following the Xenogears Perfect Works he established in 1997 but rather a modified version of it. One example: In XG the Anima Relics which are the "channelers" of Zohar's energy are created by Deus upon the crash of the Eldridge. In XS the "Zohar emulators" are already present, before the Eldridge has even been built. Testuya Takahashi has also stated that Kos-Mos and chaos will be present in the entire series (although "not neccessarily in their current form" whatever that means). :?
