By the way, it's NOT an "alternate timeline".
It's THE timeline, except it's being changed by way of time travel.
Seems from now on, what the movie depicts IS the official Trek universe.
I agree it is THE OFFICIAL timeline now, however every interview I've read seems to mention that is also an alternate, and usually even brings up the fact that is so as NOT to overwrite or trample on the first one.
