I just watched the latest movie trailer
http://www.startrekmovie.com/ and I have a new theory.
I believe that a Romulan goes back in time and kills James T. Kirk shortly after his son is born. Old TOS is wiped clean. His son then grows up to become the new James Kirk of the altered future.
The trailer is probably going to turn out to be better than the actual movie, but I will give JJ Abrams my $10.00. I think since they might be going out of their way to explain why his star trek is different from TOS might save the day. If the past is altered by a crazy half human half romulan dirt bag, then the future is erased and replaced by a new future, one that they, JJ Abrams and company, are free to explore without the constraints of TOS, STNG, DS9, Voy, and Ent.
Either way, I look forward to seeing a new star trek movie.
And the re imagined Enterprise isn't all that bad looking.
