The other could really be anything, depending on whether Tarantino’s Trek is a direct sequel to Star Trek Beyond or something completely new and unrelated to the Kelvin timeline.
After taking a couple years to rest and regroup, it looks like the Star Trek movies are back on track.
Zachary Quinto, the Kelvin timeline’s Spock, previously said that there were three different scripts being worked on in the Star Trek universe: a direct follow-up to Beyond, Tarantino’s, and another.
But Paramount gave no clues as to which of these they were going for, so right now it’s anyone’s guess.
