It was never a given that Abrams would return to helm a third "Star Trek" film, but when it was revealed the filmmakers considered the project a trilogy many believed he would. Clearly, it would be shocking to see Abrams to go from "Trek" to "Star Wars" and then back to "Trek" again.  So, who's next? Paramount has much bigger concerns with just making sure "Star Trek into darkness" turns out to be the global blockbuster everyone is expecting.   Will a Bad Robot alum take over?  It likely won't be anyone major (no people,  David Fincher is not directing a "Star Trek" movie), but there's a long list of secondary players who will be willing to take the gig.
