I have real high hopes for this game, seeing as it is being developed by tri-crescendo. They were the people who worked on Baten Kaitos 1 and 2(two VERY under appreciated RPGs for the Gamecube, I hope this game won't end up like those when it comes to sales).
They also did sound for the Star Ocean and Valkyrie Profile games(which were kickass, btw) along with the above mentioned Baten Kaitos games.
Judging by the demo, I'd say it plays a lot like Star Ocean, which is why I'll buy this game sometime by the end of the year(I'll be busy with Halo 3 for a while).
