My wife and I saw both the teaser and Cloverfield after lunch today... we enjoyed both.
My guess would be that nothing we saw in the Trek teaser will end up in the final movie though. What was there was totally a set up for the "under construction"
tag line. While that may be close to what the final version of the Enterprise may end up looking like, there really shouldn't be any need for construction of that type on the Enterprise. She should just be getting handed off from Pike to Kirk.
If anything, I would bet that they still haven't finalized what the Enterprise will look like for this movie... in other words, it is still under construction
So yeah, I like the teaser... it was very dramatic and all, but I doubt that we really learned anything more than what we had known before it's release.
