I see the trailer and... meh. I'll watch the film when it comes out, but I'm not seeing many clues here, just mostly worthless eye candy that just shows a lot but doesn't reveal anything. What is with the silly looking gun arm on the villain anyway? What is this? Ironman 3?
As for the ships in the water shots, the rising ship looks like the JJ Enterprise to me because I am looking at my Playmates toy sitting on the shelf at almost the same perspective. Every detail on the nacelles lines up. And there IS a saucer popping up through the water in the background as well. It looks very much to me like the shot they did of the Enterprise popping up out of Titan's upper atmosphere in the first film. So what, are they going for a VTTBOTS vibe now with each film having the Enterprise surfacing? As for the other image, it looks kind of like the movie refit ship (straight pylons instead of curved ones). I'm not going to begin to speculate on it though, or get into a long discussion about the merits of starships, water and the like.
As for the blonde, it could be any one of four women... Dr. Dehner, Nurse Chapel, Carol Marcus (doubtful as I don't think she was starfleet) or Rand. Who says Rand HAS to wear red? Heck, it could be Ruth or Janice Lester for that matter (or even Marla McGivers if the baddie is indeed Khan). It could be any other blonde woman they decide to stick in at the whims of the writing staff as well.
