Yes Kiefer Sutherland will voice Big Boss, Naked Snake in Metal Gear Solid 5
Konami announced the voice-actor that will be playing Big Boss in Konami’s highly anticipated installment to the ‘Metal Gear’ franchise, Metal Gear Solid 5.
Kiefer Sutherland was the leading assumption for the voice of Metal Gear Solid 5, the actor does have a rather unique voice and when the GDC trailer was shown, many people recognized the voice right away. Though no one really knew who Ishmael was (the bandaged Snake who will late be revealed as Big Boss in Metal Gear Solid V).
Of course when you are talking about Metal Gear title you also have the chance that there could be two-snakes, 3 clones, a new clone, an Ocelot half-blend or something new. So we will wait to judge anything until we know what’s going on. Since this is a Metal Gear game, that should be on our fifth play-through.
