What I think is: So we know that were in all 8 clones of Big Boss but only 3 survived, Solid Liquid and Solidus. But in the trailer, these 4 guys all have numbers on their heads. What if these cyborg-ish guys are the other clones that were rejected,and then turned into cyborgs? What if ‘V has come to’ refers to the 5th, maybe perfect clone?
