Also, we're talking about a Teaser Trailer, and Teaser Trailers often don't have any actual footage frm the Film, so, if that's the case, if it's just going to be a Logo, and a Voice over, and maybe some reused footage from the First movie, I wouldn't expect that to be in 3D.
First full trailer (Possibly with The Hobbit?) yea, maybe it'll be a 3D trailer.
I think you have to contextualise what this film will be, promoting it with a 3D trailer, whether its teaser or not, is an unparalleled opportunity.
I think they'll go with SFX shots like TOS opening titles where the Big E flies towards you at speed, that sort of thing, a Starfleet emblem in space that has depth never seen before etc etc.
I haven't been to see a 3D film where there weren't 3D trailers, hence I ask again, what's coming out in the near future in 3D because that's where the trailer will likely be.
