Re: Halo 5 speculation (spoilers for Halo 4)
Yeah, but that was the whole point of Halo 4; Chief went through an emotional journey and by the end of it started to realize that he can show emotion. I really think that he'll start to be less of a machine and more human.
Also I'm going to throw it out there; Blue team will make a reappearance and we may see some squad dynamics in both gameplay and story. John was really close to them after all.
