Gamespot also posted a preview along with screens of Light Weight’s PS2 Kengo title.
A slice:

Though the basic gameplay is the same, Lightweight is making several changes to differentiate Kengo from the Bushido Blade games. Foremost among these changes is the new ki, or spirit, meter, which gauges a character's remaining stamina and attack power. Repeated use of special moves, for instance, will drain ki, so more powerful attacks will require judicious use to remain effective.
