Preview: Metal Gear Solid V: The Phantom Pain (360, PS3, PS4, XBO)

I'm unclear as to why Konami releases details of Metal Gear Solid game. Does anyone really know what's going? Never mind the larger narrative and connection between games in a series that spans more than 25 years, I have trouble following what happens moment to moment. So, when Konami provides some of the story details of Metal Gear Solid V: The Phantom Pain, which involves Big Boss waking from a coma and heading into Soviet-era Afghanistan to investigate (i.e. destroy) the "mysterious" XOF organization my brain simply turns off in order to protect itself.
