Realistically, I think the best one could hope for is a release as an audio adventure. At very, very, very best, if the Gods smile on Trek fans, a direct-to-DVD animated adventure in the vein of the DCU movies - which have been released despite the live action Batman, Green Lantern and Superman movies. But we're probably not really comparing like with like.
It would be great if we could get something made like the DCU animated features. I don't know a thing about the copyright and other marketing issues, amd frankly, I don't care. I just know I would pay real money for one last adventure for the crew of the USS Enterprise as voiced by the original cast!
