Metal Gear Solid V: The Phantom Pain will release worldwide on September 1, 2015.
"I always say 'this will be my last Metal Gear.' But the games in the series that I've personally designed and produced -- Metal Gear on MSX, Metal Gear 2, Metal Gear Solid 1,2, 3, 4, and Peace Walker, and now Metal Gear Solid V -- are what constitute a single Metal Gear saga. With Metal Gear Solid V, I'm finally closing the loop on that saga. In that sense, this will be the final Metal Gear Solid. Even if the Metal Gear franchise continues, to me, this is the last Metal Gear."
The rules of the internet are simple: If you don't want folks to know stuff early, be careful how you post it on the interwebs. Are you hyped about the next Metal Gear?
