A few did think Kyo. Someone on ON also mentioned Karate, I believe.
Really interested in seeing their moves, however. EX Kyo stands to be one of the more complex characters in this game, and they have a LOT to draw from for the real Mr. Karate. Looking forward to a remix of his AoF1 theme, too.
SNKP might not be at TGS, but this might be a good week to release some info anyway. Atlus USA is the only branch of the company involved with XIII, correct? The JP side is being handeled by SNKP themselves. Though, the Atlus US KoF site seems to be updated at the middle and ends of a month, and the middle is coming up soon.
