Orcis Trek 3
From various articles/rumours etc it sounded like Orcis script (which he was going to direct) was going to be very 'Star Treky' dealing with alternate timelines/realities - so something like Days of Future Past/Terminator Genysis/BTTF2 & Yesterdays Enterprise/All Good Things/Trails&Tribulations. And of course like ST09 touched upon in order to reboot the universe, but in much greater depth and maybe not with time travel as time travels been done 3 times already in the movies (or 4 if you count Generations) and as recently as just the last but one film (but its not been done yet in the AGT/DOFP consciousness type way) and would've involved Shatner in a fairly prominent role (at the time he stated JJ had informed him hed be in it) either as actual Kirk 'Prime' somehow, or as a future version of Pines Kirk (maybe Shatner would've been zipping across timelines/interacting with familiar events like Picard in AGT?). Nimoy was also rumoured as going to be involved (before he died of course). And it may have potentially wrapped up/ended it as a trilogy Nolan Dark Knight style (which i think Orci had previously stated the nuTrek films were sort of following as a template) - so maybe the alternate universe was somehow to be concluded (but not necessarily the end of the film series) maybe even to make way for the new TV show set in the prime universe? e.g. ties to the events of the first film - an 'all roads led to here' type thing involving links to the Narada and its disappearance at the end of ST09? old Spock returning to the Prime universe? ShatKirk?, maybe even TNG?
That stuff (if it was to be that) sounds very 'Star Treky'/fanish (possibly the grounds on which Orci left) and something that would make sense for a fan like Orci to come up with (taking into account the previous 2 films stories and comparisons to TDK trilogy) especially with it being the 50th anniversary, evoking call backs to Treks rich history (like Dr Who 50th did). I'd have much preferred that kind of stuff to what I seen/heard so far of STB (which looks as its going to be like a big budget version of Omega Glory meets Avatar/Insurrection with a Generations style crash and emphasis on the prime directive. no dealing with ShatKirk, alternate timelines, etc.)
Perhaps Paramount didnt want to go with it as they didn't want to be dealing with 'Prime' stuff (esp without Nimoys involvement due to ill health/death) and potentially conclude the rebooted alt universe, and just wanted to proceed as if it were a new ongoing universe (potentially leading to ST4/5 etc as the cast are signed up to) with an all new adventure unrelated to any complicated alternate universe stuff and call backs to what happened in the 'Prime' universe (which was a central aspect of both ST09 and STID)
Maybe IDW comics will do Orcis ST3 as a 50th Ann special - 'Beyond Darkness?' (like what happened with Harve Bennetts Trek VI Academy movie which was sort of done as a DC comics special at the time of Trek VI/the 25th anniversary)
