Re: STID "tracking" for $85-90 million opening [U.S. box office]
Well it is possible JJ could direct the next ST film. If SW is scheduled to come out in 2015, that would mean it would shoot in 2014. So a shoot starting mid 2015 after SW comes out is entirely possible for a 2016 release.
It's already been mentioned that he's going to have some pretty heavy post-production and editing work to do on SW, though.
And that's my opinion.
