Ok I've been rewatching the trailer....noticed a few things...
1. Hard to tell but appears the bad terminator driving the big truck is the same guy in the small truck...could be wrong but does seem like he's taking the form of a character we've already been established with.
2. I thought the bad T had morphed out of the drivers seat into the hood of the truck....but nope....there's apparently 2 of them as there's still a terminator sitting in the chair driving while he's outside the truck...thought it was funny the bad T let in the truck shifts gears while the other T is separating himself from him
3. When Linda shows up and starts blasting human bad T, he starts running but not towards his target original target....my guess is that he's running back towards the exoskeleton T and if so guessing that their abilities are weakened when they separate from each other
4. Good girl T looks like she beats the hell out of some cops naked so must be right after she travels back in time.
5. The lines, "why do you care what happens to her?" "Because I was her." Sounds like something happens to John Conner but after judgement day is prevented.....then something else swing into play causing the fate of judgement day to re-occur and this new woman they're protecting is who will carry the baby of the new resistance leader
What I don't understand is....how are they going to explain Arnies back? He can't be the same terminator from T2 because of this scene that no man ever cried at ever....
