The teaser for the last one came out 11 months before the movie was scheduled to be released at the time. For this one that would have been July. I now think however that it will probably come out in November.
It's NSFW. That's all I'm gonna say about it. I didn't watch ANYTHING for ST:XI. That was cool, but this time around I'm going to be downloading any teasers/trailers directly into my brain.
Some of you have probably seen this already, but in the comments on this article: http://trekmovie.com/2012/08/06/star-trek-vegas-con-2012-trekmovie-com-panels-preview/ Bob Orci hints that there may be a trailer soon. Of course, he could just be talking about a trailer to be released in several months, but I'm hoping it's in the next few days at the Vegas con.
it a teaser video. It technically is more than a screen grab. http://teamcoco.com/video/jj-abrams-gives-an-exclusive-sneak-peek-of-star-trek-into-darkness via The Hollywood Reporter I didn't want to add to that other thread that was a misleading title.
