There will be a third nuTrek film, but with the movie under performing Paramount's expectations, and the studio higher ups being irked by the Star Wars thing, there's still hope JJ won't be doing the next movie.
Really though, Abram's isn't as big of a problem as Orci. That's the guy that we really need to get away from Trek.
Why? So we can go back to the good old days of no one wanting to pay to see "Nemesis" or even watch Enterprise
Sorry, Star Trek Into Darkness
is the most fun I've had watching Trek since The Undiscovered Country
was released in 1991. I will gladly welcome back Abrams, Orci, Kurtzman and Lindelof.
