There won't be a 3rd film.
STID will get overwhelmingly bad reviews and word of mouth after it opens in the US. It will flop in the box office and Abrams will be fired.
It will take another 2 years but Paramount will realize the mistakes they've done, pick up the phone and get B&B back.
LeVar Burton and Brent Spiner will write & produce a 25th century story. Michael Dorn will direct.
or the Borg with Cumberbatch as the Borg King.
