The first part of the game will be a pure prequal.... us playing as BIG BOSS. It'll show how he reached the status of LEGENDARY SOLDIER and all, and what actually happened to him. And After 50% of game complition.....the story will change and SNAKE EATER will actually become a TRUE SEQUAL. We will play as Snake...."In the same jungle area, and same places, but it'll be present time....not 1960's. So it'll be 50 years later or something. That could be a SIMILAR SURPRISE KOJIMA HINTED AT. Because it is a Character change but because Big Boss and Solid Snake are look alike....it wont make much of a difference. All this also include that when playing As Solid Snake, we'll see the parts of jungle and some building which now have been torn down or destroyed because of the war that happened there 50 years ago. It'll be cool..... but all this is my assumptions.........
