Well there was suppose to be like 6 or 7 Xenosaga games, but it'll never happen.
The decline in sales pretty much ensure that.
There are many other reasons actually. Xenosaga was envisioned as a 6 part series which spanned thousands of years, involving different story arcs, as detailed in a similar timeline in Xenogears Perfect Works.
From the start, before Episode 1 was released, Takahashi already mentioned that not every Episode would definitely be a game. His plan back then was that they could branch out and tell major story arcs in-between huge gaps of time using novels, comics, and other medium.
Unfortunately the series had serious production issues in terms of budget and delays. This resulted in each Episode of the games covering less material than originally intended. The story of Shion's era was most likely not meant to have spanned 3 episodes, but 2 instead.
But after Xenosaga Episode 1, Monolithsoft had an internal shuffle in terms of what to do with the Xenosaga series. This resulted in Takahashi taking a back seat in producing the series, while younger staff took over and tried different things.
This pretty much fractured the fanbase beyond repair, and resulted in the series ending in Episode 3 with the conclusion of just Shion's story arc.
