Let's start with the obvious reason we may never see another Terminator movie: The past few sequels were pretty much total train wrecks. Things started to go downhill with 2003's Terminator 3: Rise of the Machines, the first sequel to make it to the big screen without original director James Cameron at the helm. The movie wasn't terrible, but looking at the story, it was wholly unnecessary. It was basically about trying to delay Judgement Day, then realizing it was inevitable. Nothing changed.

Splashy action director McG was hired to helm 2009's Terminator: Salvation, which somehow managed to make the most compelling piece of Terminator lore (the action-packed, future-set battle with Skynet) utterly boring. A full-on pre-boot was attempted with Terminator Genisys, which served as a muddled throwback to some visual elements from the first film that only seemed to remind fans of what they were missing. Sequel after mediocre sequel has taken a toll on the fanbase, to the point that proposed Genisys sequels were actually dropped from active development after the critical bashing the film took after hitting the big screen in 2015.
