Full STAR TREK trailer indicates hands against glass scene is actually Spock and Cumberbatch. If he’s Sybok… Well, kudos.
That said, Cumberbatch does NOT have Vulcan ears. Hands against glass scene seems to be Cumby in the brig.
Trailer opens with Pike VO, telling Kirk he has courage but no humility, and someday that will get him and his crew killed.
Oh yeah: there’s space stuff in the full TREK trailer. Space combat. Guy in a space suit zooming around.
In addition friend (and sometimes contributor to) TrekMovie Jordan Hoffman confirmed a few more details via Twitter DM:
Cumberbatch was definitely shown in some sort of brig
Chekov (Anton Yelchin) appears in a red tunic (instead of his regular gold tunic)
Someone wears a EVA space suit with similar design to the one used in Star Trek: The Motion Picture
