Imho - if true - that would be the worst case scenerio, I really was hoping for something NEW this time. I am so tired of Star Trek films trying to copy themselve, ever since First Contact they only go for "like Wrath of Khan" and it NEVER works.
Honestly, JJ. Abrahms did a good job on the reboot, but I do feel they better had someone else write and develop the sequel. Obviously he is way to busy with other stuff and it seems they cobbled together a script at the last minute.
It seems that Abrams may have been referring to Del Toro's involvement as untrue, not the inclusion of Khan—because Vulture backs up the original Latino Review report that, yes, Khan is the villain of "Star Trek 2." Developing, as they say.
