Something i missed on first glance on the RSG official KOFXIII website is this new trailer showing off what i think may be the console intro movie, and you can catch a small glimpse of some of the new stages.
One thing i did notice in the video is the Kyokugendo gym stage the background looks static...I hope that this is just an early in development version of the stage, as it would be a shame for the background to be static.
Also notice one of the new stages looks like it might possibly be Adelheid's stage???
[Edit]: Also special thanks to Evil Yagami for pointing out the trailer to me!
