That's probably all it is: rumor. That would kill the Chief's image for people who wish his face to remain a mystery, and if his face is revealed in Halo 3, then it would ruin it for teh poor noobs that don't play the game before buying possible spoilers. Not calling anyone here a noob, though...
I don't like the controllers... to gaudy and adolescent looking for me. I would have much preferred a controller with MJOLNIR color schemes, or one that looked like dual M6G's. That would have been sweet... The headset, though? I only have the awkwardly fitting wire headset, that barely fits my odd head, so a wireless Master Chief headset? yes.
