^^^ Hmmm...
Well, looks like:
1. They came up with a (potentially) clever way to make good use of the Abraham and Co. story arc (I won't spoil it, but in the comic, it's a bit of a let down...)
2. Terminus appears to be unrelated to any specific comic book settlements or story arcs.
3. Hard to tell from a trailer than really concentrates the undead carnage, but looks like they upped the budget to spring for a better array of really gnarly zombies.
So far, I'm feeling optimistic about the upcoming season...
