Also where's John? Is he dead or doesn't Sarah just not think he needs protection anymore?
My current guess based on the small tidbits in this trailer is that John isn't the dude anymore. Judgment Day was delayed long enough that his moment as leader of the resistance has passed. That future didn't happen, it's no longer his responsibility. He may be off somewhere living a normal life now, or maybe not living at all. A new judgment day could have got him this time because instead of hiding in mexico preparing for war, maybe he was hanging in new mexico raising kids.
But while John may have moved on, Sarah never could. And now 20+ years later, someone comes back from a new farther future war. But this time, instead of telling stories of a great John Connor, their story is of someone new who rose to the challenge. And now Sarah is protecting the mother of that person.
And that's what Sarah means by saying (iirc) "I
was her." A new woman is now in the position of being the hunted mother, and Sarah is determined to help her life turn out better than her own. The future we thought we knew is no longer valid, but a judgment day is still coming.
And this sort of soft reboot premise is their new platform for sequels.
We'll see if that guess pans out later.
Is he even a Terminator? How would it even make sense. I think I read somewhere that he's playing the guy the Terminator was modeled off, but I'm not sure if that's correct.
I'm really wondering about this too. There's conflicting information on that. Most rumors have him playing both the human
and an
evil terminator, but so far only a
single Arnold form has been seen anywhere, and set photos
might have shown him with some metal scrapes on his forehead. So the rumors aren't really matching up.
But Arnold is going around telling people that terminator skin can age like normal skin in this movie, so I guess all we can assume so far is that he is playing a terminator. And
seemingly a nice one, from what is seen in the trailer.
But that could always be misdirection. I would be delighted if he ended up playing a human in this. An old army tank who once upon a time was contracted by Cyberdyne to use in a new project. Recruited in this movie similarly to how Miles Dyson was once recruited by Sarah. However that does introduce problems, like why is he not in jail for the events of 1984 and 1995 that would inevitably be pinned on him.
But following the line of thinking from my prior guesses about Sarah/John, I fear if he's human that in the new future this guy never even got used as the basis for the 800. That development would be disappointing for fans, but could be used strategically in order to continue building their new sequel platform. Now a new guy is the 800. Writing out all the old characters and replacing them with new ones.
I wouldn't like it but I could see them trying it.
