Well, on a different note, Liquid's hair was sun-bleached and he still had both arms at the end of MGS1. It would be pretty terrible if it turned out to be a nightmare sequence too so I'm hoping for ingenuity on Kojima's part, which is probably asking too much.
When I first saw the trailer, I was too absorbed in how badly pacedit was, probably to disorient and confuse the audience but okay, to recognize what it really was. Welp. Then I looked back and it was clearly Kojima-influenced in cinematic style.
