From this picture several things appear different to what we've seen previously:
1. Her parka looks vastly different. First, it doesn't *appear* to have a coyote fur lining...it looks like a shell only. Second, it's got pockets on the chest area, as opposed to the bottom of the coat area as seen previously. Third, it doesn't appear to be as form fitting.
To me it looks similar to a US Army Fishtail Parka... except for the pockets on the chest area...they don't have those. Also there are shoulder eppaulets, which the Fishtail Parka doesn't have. M65 Field Jacket, perhaps? But no... because this coat appears to have lower "slash" pockets, and an M65 doesn't have those. Gahhh! I give up
2. She seems to be wearing a Blackhawk Style Tactical Thigh Holster, rather than the leather holster from the previous game.
3. It looks like she may have a Chrome Plated M-9 as well.
4. These may or may not be the Charles Street Boots. It's impossible to be sure from this one pic...we can't see if they've got the buckles at the ankles or not. But I don't recall them having speed lace fittings on the upper part of the boots... i could be wrong.
Of course this could just be another concept picture, and not representative of the final in-game model. But if nothing else it provides options for those who don't have luck finding the "exact" items we've seen so far.
