Hideo Kojima has revealed just what "Project Ogre" is with The Phantom Pain with a trailer at the Spike Video Game Awards 2012, though this could be a working title for Metal Gear Solid 5.
The game is supposed to be developed by "Moby Dick Studios", but the project page is a dead giveaway.
It states, "Moby Dick Studio is a game developing company operating out of Stockholm, Sweden. Moby Dick Studio was founded by CEO Joakim Mogren who after years of working for a major American developer brought together people out of various game studios from around the Scandinavian area to start something new."
"Joakim" is an anagram for Kojima, and one might notice in the last name "Mogren".
More evidence is in the title, which shows hash marks. Some have noticed that "METAL GEAR SOLID V" can be seen faintly in the background.
Kojima certainly loves having fun with people.
