I'm not sure that is the Enterprise. The nacelles look weird to me unless it's just the angle, and the fact that the trailer cuts away from it before you can tell what the registry is makes me think they WANT people to think it's the Enteprise, but it isn't.
I just watched the High-Res iTunes trailer. The last couple of frames you can see it says 1701.

The other ship crashing into San Francisco Bay at the end looks like a updated huge version of the NX-01 with the 'The Motion Picture' Enterprise nacelles. Go back and look again. I detect no secondary hull.
I agree. I just analyzed the hell out of it too!
