I seem to remember a report that JJ wanted to do a new TV series that would run alongside the movies, but that the studio said no. I'm not sure if that's true, but it sounds like something that JJ would do.
Kurtzman and/or Orci have mentioned wanting to do a Series, but, no rejection or approval (Or for that matter a Solid pitch) has been confirmed by anyone
Many of us have theorized that the most likely scenario, would be after STiD proved to be a success (Which it now has), that a Series (Probably animated, not Live Action) would be greenlighted, so that it would be able to premiere shortly after the next movie premieres. No indication that this is going forward at this point, though. (Which would also be a 50th Anniversary Celebration, as well, hopefully)
One Day I hope to be the Man my Cat thinks I am
Where are we going? And why are we in this Handbasket?
