I thought that desolate area was on Kronos. At least that's how it's captioned over at Trekmovie.com's shot-by-shot description of the trailer. Of course, they're probably guessing, too. The link is below, just scroll down to the picture in question.
I certainly hope Admiral Marcus isn't involved in this in some way as a bad guy. We've seen too many "bad officers" in Trek. Of course, he could be the person or one of the persons responsible for the "crime" Harrison says was committed (or course, the "crime" is probably a gray issue, too).
Looking at those pics made me consider something. In the picture of all the officers and captains, they are watching something on their screens. From what I can tell, It looks like the same thing.
Look at the latter pick of Kirk saying,"This could just be the beginning".
Whats the connection here?
