Video Games Xenosaga 2: a rumour?

Okay, the game itself is not a rumour. It obviously will turn up sooner or later. If you thought that was the topic of this discussion, just go away.

I heard a rumour recently on another site (that will remain nameless) that for the upcoming second Xenosaga epic master composer Yasunori Mitsuda has been replaced by Yuki Kajiura of .hack fame. Can anyone confirm or deny this rumour and reveal the truth?
