To be fair, Abrams isn't saying that Shatner will be in the next movie. (And it's early enough that if interviewers asked, "Could Gracie the whale and Squire Trelaine dance together in the next movie?" Abrams' response would probably be, "Maybe.") But still, this is the first indication from Abrams that a long-awaited Shatner cameo could happen in the next movie. And he even has a rationale for it.
Abrams told MTV:
"The point of creating this independent timeline is to not have the restrictions we had coming into this one. And one of those restrictions was that Kirk was dead."
The second name that came up was whether or not they'd be bringing back the most beloved villain in all Trekkerdom, Khan.
As for Khan, many people believe that since Kirk never stranded him on Ceti Alpha V, the character would no longer be the same villain we saw in Star Trek 2. But Abrams argues that it is still possible to feature Khan as the villain in the Trek sequels: "[Kirk and Khan] exist - and while their history may not be exactly as people are familiar with, I would argue that a person's character is what it is. Certain people are destined to cross paths and come together, and Khan is out there … even if he doesn't have the same issues."
Well at least it's good to know that they are toying with the idea of bringing him back. I feel like no matter the time rift, Kirk and Khan are destined to be enemies. If not in one way, then in another.
