It's most likely just a Community Manager that doesn't know MGS very well, and had almost no directions on what to post, except "there are new characters". It's most likely that he choose this picture because he didn't even analyse it one second.

I already pointed out here http://metalgear.wikia.com/wiki/Thread:32622#15 (that was before i registered) all the evidence that it is clearly Kaz. At this point there is almost no possibility that it could be someone else. Even if that were true, by the time the post was made, the Microsoft section showing pretty clearly showed Kaz in the trailer, so there wouldn't have been any excuse for that kind of mistake.
