I've just watched the trailer shown at E3 and picked up a few things so i want to turn this into an info/rumour thread about the game.

Here's what i picked up

Only scenes show are in a small village dock and jungle
It's set during the cold war
apparently over the years 1961-1964
due to the time period this can't be solid snake as we know him
this is backed up by a missing eye in the trailer, my only idea is that this is big boss
The graphics haven't improved massively
the game engine does seem to have more active surroundings climbable trees rushing water animal life.
You eat snakes?
