History
In December 2011, Kojima talked about initial ideas for his new game's storyline and how the staff insisted on him being involved in development of the game:

"Metal Gear Solid 4 wrapped up in 2008, and the dev team took post-project time off right after that. But, of course, we were in a situation where we had to start planning for MGS5. So I started coming up with several ideas. I had several ideas for a game featuring The Boss and the Cobra Unit during the Invasion of Normandy. I then handed these plans over to the team so they could take over and make the game. I presented my ideas to the team during the summer of 2008. However, simply dropping MGS5 on the younger staff members was a bit heavy and there was resistance to doing it without my involvement. At the time, I was working on a new project. It was during the planning phase of that project and I wanted the staff to take charge of the new title. There was resistance to that idea, though. It was then that someone proposed the idea for what would become Rising. It was a game based on Raiden's story, since MGS5 had too much weight to it. It would be a side story that the team felt more comfortable working with."

On June 20, 2012, in an interview with the IG Magazine, Kojima dropped more hints stating: "There will be a MGS5 with the new Fox Engine, but what we showed was not the in-game play, or something like that. It was only a demo that we had developed internally and that we released because the lighting and all interactions with the environment had fooled everyone." Kojima has promised that the next ‘proper’ game in the series will be espionage, "About Metal Gear Solid 5, I can tell you two things...There will be much question of infiltration, espionage and convince people to give you "a favor" in the last MGS." He also pointed out that "I liked the idea of ​​social interactions of Deus Ex: Human Revolution, but we'll see." He also stated that "We have not yet finished with Solid Snake, despite the fact that I wanted to let him die at the end of Guns of the Patriots."

At PAX Prime 2012, Kojima announced that Metal Gear Solid: Ground Zeroes will be a prequel to Metal Gear Solid 5.
