Metal Gear Solid V: The Phantom Pain Has A GDC Trailer

It seems GDC has been in quite the tizzy this morning as result of this Metal Gear Solid V: The Phantom Pain trailer. On a related note, I have been in quite the tizzy, as anything Metal Gear related gets my jibblies all jangly.

I have a few theories as to what's going on in the trailer, but trust me, nobody wants to read my 5,000 word thesis about nanomachines and comas and Big Boss' glorious facial hair. But, to put one theory to rest, how DOES Big Boss  have such glorious hair?

Spoilers: Nanomachines.
