I saw that video as well. If any of it is true then this movie can f*** itself.First off how reliable is this Midnight's Edge? Cause I'm hoping this is false:

He's saying in the context of the movie, Skynet is no more, but it didn't just send the T-1000. It sent multiple T-800s in case the T-1000 failed. They activate when the T-1000 goes offline, and shortly after the events of T2 one finds Sara and John in a bar and blows John away. So Furlong is only there to do mocap to be de-aged to the age he was in T2. Anyway, If I'm understanding this correctly, once a Terminator fulfills its mission its CPU, um, automatically switches to r/w? So that particular Terminator "feels remorse" and helps Sara kill the other T-800s. Ah and it take the name Carl. That's who we see in the trailer when Sara visits an older Arnie.
But someone, or rather something, like Skynet is like the lightbulb, destined to exist. So Legion comes to be and fills its void and everything repeats itself. There will be a future war, that girl is destined to be its savior the same way John Connor was fighting Skynet, enter Rev-2 (Luna) and Female Reese.
So, again IF true, they are following a lot of the beats of T3. spoilers:end of spoilers
Cause that's exactly how we got the T-850. In exposition it was pointed out it killed John but once it did, hey, free Terminator for John's wife to use and send back in time. Luna as a more advanced T-X...other lieutenants being hunted = the "new John Connor" being hunted.
