The first set of screens are in for the XBLA remake of the first Soul Calibur game. That's the Dreamcast one and not Soul Blade of the PSone era.
We reported a few weeks back that Namco had confirmed the title for Xbox Live Arcade, saying, "Leaderboards yes. Online multiplayer no. This might have something to do with the fact that Soul Calibur IV will be out soon after and no one wants to shoot themselves in the foot do they?" Probably not.
