Dont know if this has been said, but it has been confirmed that Jeff is gonna return as the voice for “Double kill, killing spree” etc.
He said on Facebook a while back that he had just got done a voice recording session, so yeah.
@bGanci
Yeah it actually pretty much has. Not directly, but Downes did the trailer voice, and has talked about the Halo 4 Chief’s character in the past.
Though he may have confirmed it before, not sure…
This is known. The Voice of MasterChief though has not been confirmed. 
Alright, my mistake. Let this thread die.
It would be awesome if Bill Nye did the announcer
But I like that guy to
I hope you guys are right. Wouldn’t be Halo without him…as sad as that sounds, you know it to be true.
