At this very moment Kojima is working on a new game, of which very little is known. Usually we don’t get more information than a photo of Kojima’s lunch on Twitter, accompanied by the text that he’s having a ‘Project Ogre’ lunch meeting. However, over the last few years we have had little snippets of news regarding Hideo Kojima’s mysterious project. Because it was easy to miss some of them, here is all the information collected in one place, rumors separated from facts.

Metal Gear Solid V: The Phantom Pain and Project Ogre are one and the same thing. Kojima confirmed this in an interview held during E3.
So that whole "new IP with interconnectivity between PS3 and Vita" schtick from 2011 WAS a lie...
I have a feeling the taboo subject the game covers are to do with child soldiers.
Here's an idea...
Don't give your new game five different names. That's the dumbest thing I've seen Kojima do.

Hideo Kojima says Metal Gear Solid Ground Zeroes isn't the mystery Project Ogre. So is it wacky to assume Ogre (or MGS5) might launch with the PS4?
Nowhere in the article does the author say Project Ogre or MGS5 will be exclusive. In fact, he knows they likely won't be exclusive.
Try reading the article rather than just headlines. You know, just a thought.

"Konami, Kojima Productions and game development luminary Hideo Kojima recently announced the next entry to the long-running Metal Gear Solid series, Metal Gear Solid: Ground Zeroes, with a gameplay trailer and further details revealed this weekend at PAX Prime.
Unsurprisingly, fans and gamers have gone crazy over the news with tons of speculation and exciting surrounding the game, as well as a lot of questions.
There’s one specific question that Hideo Kojima is “sick and tired” of answering though."
a metal gear title set some time between ww1 and the end of ww2 would be quite welcome by me. let's see the cobras in action, in their prime. it'd be sweet to play as different characters too after you beat the game multiple times in order to switch up the game play in fresh ways, such as getting to be the end, the fury, or the sorrow. three very distinct styles.
