The Game Rating Board in Korea also rated Marvel vs. Capcom 2 with Microsoft as the publisher. The latter implies this rating is for an Xbox Live Arcade game. Many multiplatform games get rated twice so this isn’t representative of a PlayStation 3 version. Add this to the ESRB, Madcatz joysticks, and Xbox 360 achievements that squeaked out and you have a mountain of evidence pointing to a Marvel vs. Capcom 2 port. Pretty amazing how far and wide information about unreleased games can be found these days.
