i just thought of something. what if the new white guy in tyrese's group is meant to be a doppelganger to rick? he's the closest looking guy to rick in the whole series that i can remember. on top of that, they both just lost their wives and have a son looking up to them. the difference is rick is trying to do the right thing despite it all, while according to the sneak peek the other guy is trying to kill them all and take over, it'll be interesting if that's what the writers are aiming, and see who wins and who fails.
