http://media.1up.com/media?id=3186285 In an Independent PlayStation Magazine (also known as PSM) article titled "The Definitive Version, Exclusive to PS3" on http://www.1up.com/do/gameOverview?cId=3148473 the female character model was discussed by Stephane Baudet, Studio Director for Ubisoft Annecy, as "PS3-specific content."
Yet, a Ubisoft Community manager, posting on the site's official http://forums.ubi.com/eve/forums/a/tpc/f/2771048463/m/5021010725?r=2931070925#2931070925 indicated that the female character models weren't specific to the PS3 version of the game:
The female spy skins will be part of the SCDA DLC for the Xbox 360 as has always been the plan. I do not have any more information about the DLC at the present time but I was able to confirm that much.
