Can we now officially assume that there will be no more xenosaga games.

On the xenosaga forums many of them remain optimistic about them going on and making a 4th game in the series after the sells for Ep. III were decent.

But now with it being close to two years since ep. III was made and with a whole new system generation coming to pass can we now safely say that their is no chance of another xenosaga game (at least in terms of a game that will continue on with the storyline).
