Metal Gear Solid 4 is barely off the shelves and they're already discussing a fifth installment in the main series - good news for Metal Gear freaks.
Regarding what would be left to tell in the Metal Gear saga, MGS4 producer Ryan Payton says there's "still a lot of room for filling in the gaps as far as Big Boss is concerned." And on the specific topic of a fifth game, he says "There are some misunderstandings that this is the final Metal Gear game. But it's really the final chapter of the Solid Snake story. That's all."
Indeed, director Kojima himself has stated (after many contradictions) the series will always be around. Which, in an often volatile industry, is kind of nice to hear. Now, while he has confirmed his involvement with the next title, he won't be in charge of it as he has been up until now. More or less, he feels it's time to "pass it down." Should be interesting to see how it turns out without Kojima at the helm.
Payton discussed the realism that would be involved in the next title, stating someone else will be the star:
"I'm happy we could wrap up Snake's story in MGS4 because it gets to the point where if we continue on with Metal Gear Solid 5 with more Solid Snake adventures, we'll get to the point where the game has absolutely no basis in reality. I do like the idea that this character has had four or five big missions and then that's when it ended, rather than have 20 missions where there's no chance in hell a secret agent could ever survive. He's had four or five really big missions, and that seems a little more realistic to me."
