There are differences... The city skyline for example (San Francisco) the scaffolding, the straighter nacelle pylons, the flatter area of the secondary hull between the pylons.
...what if the construction sequence from the teaser trailer is that of the TOS style E (with slight modifications) and it is used at the end of the film...
...Thus we would have a shot of the familar E being constructed in the San Francisco shipyards as a way of showing that the timelines has returned to normal...
It's a bit of a stretch, but...
I don't think it is a stretch. I had a similar thought in a recent thread and I think your theory is awesome!
I can't help but feel that JJ Abrams etc. al. has a surprise or two up their collective sleeves that will bring many of the snip-its we saw in the trailer together in a way that is pleasing to many (likely not all) of the long-time fans.
Speculation NOT SPOILER
Remember, Nero is coming back in time to mess with the timeline and introduce an alternative one. Perhaps, due to this change of events, James Kirk is kind of a loner with potential but little motivation. Maybe Kirk then (at the behest of Pike) begrudgingly joins Starfleet later than he did int the prime timeline. Pike recognizes Kirk's family history and potential and takes Kirk under his wing which explains why he and Pike have a much broader relationship than what we know from TOS (The Menagerie Part I and II). This could also explain why Kirk is still a cadet while Sulu, Checkov, etc. are already commissioned officers. So maybe Pike is the mechanism in the alternative universe that makes sure Kirk doesn't throw his life away and, instead, joins Starfleet to stay consistent enough with the prime timeline and to satisfy the quantum mechanics explanation by Orci.
And maybe, just maybe it is future Spock's mission to put history back to it's proper order and more in line with TOS. Then, Omegaman, at the end of the film we may see the Enterprise from the teaser being built in San Francisco (while possibly including Nimoy's narration of "Space...the final frontier, etc.) and we end at the very beginning with Kirk joinging the Farragut and Pike scheduled to begin his 11 years on Big E. I know - wild speculation but a fun discussion.
