I think the issue with Xenogears and Tactics Ogre were that, while the people certainly are still around, it's always a real hassle to restart a series if the publishers don't feel it would be profitable. As much as I like the Xeno universe, the Xenosaga series didn't hit projected sales and so the only did the 3 games and moved on. I have as much hope for a Xeno title as I am another Suikoden title :-/
