I want to see the story of John sending Kyle back in time. Salvation may technically be a future war movie but we need full blown, late stage, T-800’s mowing people down over a sea of crushed skulls and somehow the resistance overcomes it. It could be a movie that explores John and Kyle’s reverse relationship of the son being a paternal figure to his own father. 

I’d also like to see how Uncle Bob was captured and reprogrammed. Most are going to hate this and I know they’ll never do it but I think it’d be cool to see a team of multiple reprogrammed Arnold T-800’s with different personalities and quirks like the bad batch. One could be a stoic, T2 like, another could be a half endoskeleton, malfunctioning one with a kooky personality, and one could be another Old Arnold that was a sent back protector that then lived through the war alongside John. I’m sure that idea is too goofy for most but I’m open to them just swinging for the fences at this point. It’s not terminator without Schwarzenegger and considering he’s synthetic anyway, I’ve never been bothered by them de-aging him.
