Hey guys, i'm hoping that you could answer a question...i've read somewhere in a Google post from a yr or two ago where some guy said that certain calendar dates effect certain games. ie, He said in Kotf R2, @ Christmas time, Athena (or one of the other female fighters) wears a special holiday uniform on that day, as well as gaining new attacks. Any truth to this? I've never heard this before.
