Kiefer voicing Big Boss is okay but will take time to adjust. Honestly I dont see the point of replacing Hayter, but it's done already anyway.

I know this may not be the right post to discuss this, but I felt that Skull Face, despite very likely to be a new character, would probably have something to do with previous stories. My guess would be that he is one of those people being mentioned in the "background" along the way, just like Coldman - who was mentioned in MPO, not mentioned in MGS4 and finally revealed in MGSPW.

...Which means that GZ is most likely to be a separate release.
