Because they didn't sell the series and there was no copyright infringement. The development team behind Xenogears left and formed the company that developed Xenosaga. Even if Square did develop a Xenogears 2, it wouldn't be made by the same people and probably wouldn't live up to your expectations any more than Xenosaga did.
