The only thing we can be sure of is that, after Star Trek XI, "Star Trek: Enterprise" no longer exists. Probably "Voyager," too. I have this on good authority from an inside source. Pass it on.
Except the events of ENT occur way before Nero destroys the Kelvin.
Enterprise goes bye-bye as well. The show was a spin-off of the movie star Trek: First Contact. If J.J. Abrams' Star Trek wipes out The Next Generation it wipes out Enterprise.
Thats one hell of a paradox this film is creating. A temporal incursion from the c24 into c23 by Nero and Spock affect events a century earlier. The history of the Federation radically altered by events in its future.
Temporal Investigations have their work cut out. This could get messy.
