in the first MGS he looked like moses during the briefing.
He'll most likely be in it. I saw two diffrent versions of the infared being used. One looked fairly older than the other. Watch the trailer to see what i mean. The older version of the infared shows up during the huge fire fight in the forest. Where Big Boss throws the smoke bomb, The newer version of the infared is used when Snake is shooting at enemies by a waterfall.
