Metal Gear Solid Rising: Raiden To Get Grey Fox Skin?

As is the trend with every Metal Gear Solid Game, not too much is being revealed at the moment.  However, Hideo Kojima today tweeted some interesting images. The images are below and, as one can observe, they look like Gray Fox. Now this may imply one of two things:
a. Hideo Kojima is teasing a new MGS game based on Gray Fox
b. It’s a skin that the player can unlock in Rising. I feel that this will just be a different skin for MGS:Rising since Gray Fox and Raiden both use swords and acrobatics for killin’.
Anyways check out all the images below courtesy of yfrog.
