Hello, discussion topic.
It seems that our main villain this time around is a Starfleet agent gone rogue (cause we definitely haven't seen that before - *cough*Michael Eddington*cough*), which ultimately confirms that the rumors of it being Khan are false.
And also the Enterprise burning up and being destroyed... yeah. Considering that we already saw a scene re-enacting Spock's death from the second film, this could very well be a game-changer.
Oh, and I find this thumbnail on the video to be very pleasing.
