The North American arm of Konami just released the box art of Metal Gear Solid V: The Phantom Pain for all console versions, and you can see them below for both the day one and standard editions.

The box art reveals that the Xbox 360 version will require a hard disk, which definitely suggests that the game should come in multiple disks on Microsoft's new console, requiring installation of content from the additional disks in order to roam the open world without interruptions.
