It won't happen. Star Trek as you have known it before is now dead. You have ten movies, 726 episodes, hundreds of novels, magazines, comic books, and so on. From 2009 onward, a new Star Trek has been created, and while it keeps some of the ideas from the first incarnation, it is it's own entity; it's own identity. There will be no returning to the previous incarnation. Enjoy what you have, because that's it.
“I've noticed that about your people, Doctor. You find it easier to understand the death of one than the death of a million. You speak about the objective hardness of the Vulcan heart, yet how little room there seems to be in yours.” - Spock, The Immunity Syndrome
