Rumour: Metal Gear Solid V: The Phantom Pain to be released in June or September
Source. It's IGN, so take it with a grain of salt. The article says that the game is finished, but Kojima wants to wait and promote the game more.
You're seriously telling me that they're going to miss out releasing the game on the V/V/201V? Come on... :(
Anyway, I don't think this game needs more promotion. It's launching on V platforms (See what I did there :p) and will sell like hotcakes regardless. I need this now!
