Not to imply this is true or even credible, but the ending timeline for Ground Zeroes does mention that Les Enfants Terribles was abandoned in 1976. This is a bit interesting especially when this was completely new information for an important event in the series, and something that was not alluded to during the main game. Again, "Punished Snake" might be Big Boss, or he may be a LET clone that was deformed for some reason, I don't know. However, even in the GDC trailer which first showed Big Boss falling into a coma, Big Boss's scars were not visible at all, even though in TPP, they were deep enough to be very visible even after healing. Most likely that is Big Boss, but we have to see.
