Why jet black finish not continued
Only Apple can really answer that, but I'm thinking because the polished Space gray is in close proximity to the Jet Black color.
I don't even understand why it's being named space gray considering it looks pretty black.

Can you explain please? Sounds like it would be easier just to call it black. Unless you mean that calling it "space gray" just sounds like a cool term.
I'm not a fan of the jet black look, but I'm wondering why Apple is calling the new iPhones with the black faceplate "space gray." Looks a lot more like the matte black to me.
Personally I think Apple has limited the colors on the new models to streamline their manufacturing process. I think you will see some unique colors coming at a later date like the limited red model on the iPhone 7. Now it's wait and see.
my vote is for manufacturing process too. i'm guessing when things smooth out next year the'll look at adding more colours.
