David Hayter (Original voice actor for Solid Snake):

“Great actor, good man. The game will probably still be excellent. Like New Coke!”

A lot of people are under the impression this is all an act, and Hayter’s voice may very well appear in the game. I really have my doubts, but Kojima has shown the lengths he’s willing to go to mess with gamers…so anything may happen.

Kiefer Sutherland Is Now Snake
24 and Lost Boys actor taking up the mantle for The Phantom Pain.

September 2015 Update:
Kiefer Sutherland is the official voice for Snake. After playing through Phantom Pain, I can honestly say he makes a damn good Snake.
