While I'm excited about this, I am disappointed. I love Metal Gear Solid, great games, only thing is there isn't a lot they can do to enhance the story further, there is, however, a LOT they can do to trash the story. I'm not saying they will make a game that will ruin the story, I'm fairly certain they wont, but I personally want to see what else kojima can bring out without having Snake in his way.
Kojima is a genius, and calling for metal gear after metal gear is limiting him severely. I'm extremely content with what we have so far, the story is done, we don't need anything else (though I am very excited for Rising)
