It's probably nothing, but Master Chief's armor upgrade in Halo 4 could be a tribute to Bungie. Chief has gone through a few upgrades now, from MK. 5 to MK. 6, and in Halo 4 he will have his very own shiny MK. 7 suit of armor. With this being the first real Halo game without Bungie, do you think the "7" is a coincidence or maybe a nod to the old creators? Comment with your thoughts.
