That's... err... som kinda Non-Japan-centric promotion! There's also some decent full body shots of the Skystage Artwork, Metal Xlugg XX, and at least Ai and Yuki of NGBC. Also some vids showing off the Skystage character moves, and profile info.
May be a decent place to send questions and comments to SNKP... someone with English speaking skills should be reading there, at least!
