Originally, Kojima planned on MGSV taking place during World War II, focusing on the story of The Boss and the Cobra Unit single-handedly winning World War II. This sounded very bad ass, but apparently Kojima didn't want to direct the project himself and his staff weren't prepared to do such a heavy project without him, so MGSV became MGS: Rising which eventually became MGR: Revengeance. This setting is still completely on the table, but I've thought about a number of different time periods the next Metal Gear could in theory take place. I really like the idea of a game during the Mercenary War though, since it is relatively unexplored turf and it would lead nicely into a Metal Gear 2 remake. Plus, the concept is just bad ass - the greatest mercenaries from all over the world come to Zanzibar Land to fight off the last remnants of the Soviet Union. I can't think of any other period of time better to do a co-op open world Metal Gear title, and the country itself has a variety of different types of geography ensuring diverse gameplay experiences. Anyways, what do you guys think? What do you want next after MGSV?
