Well, the official web site for Xenosaga 2: Jenseits Von Gut Und Bose (Beyond Good and Evil) is now up.
http://www.namco.co.jp/cs/ps2/xenosaga2/while the official premire of the game isn't for a few more days a few interesting things have been revealed.
Kunihiko Tanaka will not be doing the character designs for Xenosaga 2, dispite his work on both Xenogears and Xenosaga 1. The new character designs are much more life life and far less resemble anime characters now. The official site (Linked above) will let you take a look at the new character designs.
Another shocking newcomer is Yuki Kajiura at the helm of Xenosaga 2's music. Yasunori Mitsuda will not be doing the music for Xenosaga 2 as he did with both Xenosaga 1 and Xenogears. Yuki Kajiura's works include composition of both the .hack//SIGN anime series (not the .hack games), and the anime series Noir. Though not confirmed it is safe to assume Jonne Hogg, the vocalists of Xenogears and Xenosaga's vocal theme will not be back. Vocal duties will probably be handeled by wither Emily Bindiger (Vocalist in the .hack//SIGN and NOIR series) or possibly even Kajiura's group SEE-SAW who performed .hack//SIGN's opening theme.
Xenosaga's story will involve the cast from Xenosaga 1 returning, and will also feature a lot more focus on Shion's brother Jin. It would seem that this is the final nail in the Xenogears cofin, as Xenogears episode 2 would have taken place after the Eldridge crash (Though some have continued to specualte that 10 years after the Eldridge crash would be a boring setting for a game). Xenosaga 2 will take place before the Eldridge crash (Assuming there is even an Eldridge crash in the Xenosaga timeline).
Keep an eye out in the next few days for news from the Xenosaga 2 premire in Japan, and hopefully a nice 8 minute trailor like Xenosaga 1 had.
