Sounds like MGSV is done (like rumors suggested) and Kojima put his foot down about him being done with the series and ready to move on.
To which, I'm sure Konami said "lol, no" and so Kojima finally finally said fuck you guys I'm outta here and quit, and now Konami is being pissy and removing all Kojima's prestige titles to get back at him since the company is about to go down in flames with Kojima gone.
I'm fine with no more mgs, TPP will probably be awesome and it likely brings the story full cycle and the only thing left after it would be MG1&2 modern remakes, but they'll do that without Kojima and they'll probably suck.
