canon can always be reset, Superman used to be raised by the government in a foster home, now he is always raised by the kents
There is a HUGE difference between Star Trek and comics. Comics are well estlabished in their history of being full of contradictions, re-boots, etc. Superman alone has had dozens of different stories. DC has re-set the canon of every one of their comics multiple times.
Star Trek canon has been solid for 40+ years and is quite simple to explain (unlike that mess that is Star Wars, where everything written in books is considered canon unless it conflicts with the movies):
All 5 live action TV series (TOS, TNG, DS9, VOY, ENT) are canon. TAS is not canon.
The first 10 movies are all
officially canon (although The Final Frontier is unofficially non-canon as the writers ignore the events of the movie and have actually written several canon things that contradict stuff in the movie)
There are several things that were introduced in the animated series that later became canon by being used in a live action series or movie (Kirk's middle name "Tiberius" was first mention in TAS but was not considered canon until it was used in The Undiscovered Country).
The new Trek movie may technically be considered canon, but since it is set in a alternate reality it has not bearings whatsoever on the real Trek universe (which I think Abrams may have done to avoid pissing off real Trek fans since re-booting 40+ years of well-established canon would have made him look like a p***k and been the worst mistake Paramount ever made with the franchise). This also means Uhura still has no canon first name.
Having said all that, I will see this movie one way or another just because I am a huge Trek fan (although I am not a big fan of the Kirk era, the other two eras are much better).
