Update: Contrary to what Kojima said during the GDC panel today, Konami has confirmed with Joystiq that Metal Gear Solid: Ground Zeroes and Metal Gear Solid V: The Phantom Pain are indeed separate games.
What I don't get is why Phantom Pain is coming out for the PS3/360. Wouldn't it make more sense to release Ground Zeroes (the prequel) to PS3/360 and MGS5: Phantom Pain for the PS4/720? The other thing that makes most sense to me is Ground Zeroes for PS3/Vita and Phantom Pain for PS3/360, but why waste resources on a Vita version?
