So long as the Abramsverse is profitable it won't happen.It was an alternate timeline that healed itself back to its prime focus. Let's hope the Abramsverse can heal itself similarly.
I just can't see a scenario where we go back to the Prime timeline.
All it would take is for the public and studio heads to change their minds on nuTrek and realize it's a giant unprofitable turd while simultaneously forgetting that PrimeTrek was a giant unprofitable turd towards the end AND for the CBS to need a new show because the US suddenly stopped watching crime-dramas AND Bill Gates dies, leaves CBS a billion dollars under the expressed condition they use the money to produce a new series.
That's all.
