I've been waiting for this game for a long time. I even broke my rule of not pre-ordering games before release just to get few a token bonuses. Kojima took his sweet ass time and that might have added fuel to the turmoil between him and Konami. They made him into a folk hero, but we'll see what really happened when they can finally discuss the issue after release.
I recommend listening to the "Data Files" in Peace Walker while you guys wait for the game. The self contained main story and side missions were cheesy as hell, but the cassette tapes were where the backstory actually is. It'll give you a better understanding of the The Boss's motives (aka Big Boss's mentor) and it'll probably tell you about her vision that Big Boss tried to emulate when he established Outer Heaven.
Some of the cassette tapes in the Data Files are hidden. You can find them all by defeating all the "Metal Gears" and snooping around inside the AI pods. If you can't bother, I'll post the YouTube link in a few minutes. Just remember that it'll make more sense if you've played Peace Walker.
Edit:
here's the whole thing:
It's long, so I recommend listening to it like a podcast and using some headphones while playing a game that doesn't require a lot of mental power.
