The signs are all there. The image of Big Boss was the true key to this puzzle. Kojima is using the MGS4 engine to retell MG1 and 2. I talked with my Metal Gear expert today and he immediately figured it out after the Big Boss picture was dropped. As always, take this with a grain of salt but know this, if it comes true, you heard it here first. Here’s what he had to say:
they can only be going back to the beginning. They are going to tell the story of when Snake first gets recruited into Foxhound. That’s GOT to be it because Big Boss is at the right age for that time frame. We are gonna finally gonna get to see Grey Fox in it’s element!

Good Analogy X-Rumors/Bitbag, but you’ll still be blown away when you witness what Kojima has planned for the Metal Gear series…
