A secondary title to distinguish it from the rest of the franchise?
No other "Star Trek" movie was simply called "Star Trek".
Some countries promoted it as "Star Trek: The Future Begins", taking the slogan from the posters. Won't that do?
What's wrong with "Star Trek (2009)"?
Abrams will probably just name this one Star Trek 2 to vex the fans and continuity both at once.
We've had a "Star Trek II: The Wrath of Khan", so "Star Trek 2" is fine.
I recall a joke from the creators of "Jaws 2", who said they avoided the traditional Roman numerals for the first sequel because they were hoping to reduce confusion when they reached "Jaws 11".
