What we have here is JJ & Co. spotting that 10+ year old pic someone did of their AMT model mixed into a picture of the Newport News shipyard, thinking that it was "kewl", and basing a teaser on it, then coming back and cranking out a lot of very lame excuses to justify their move.
Build the nacelles on the ground and lift 'em up to orbit for fitting? Sure.
Build the secondary hull on the ground? Okay, a stretch, but not too much.
Saucer? I don't think so. Way too ungainly to build that sucker on the ground and then try and put it in orbit. Lot easier to build it in orbit and bring the other components to it. Especially when it appears that the ship depicted in that trailer looks to be about twice the size of the TOS design, if not bigger!
As for that pic in "Parallels" that so many folks are jumping over as "proof", anybody remember that knock-down-drag-out donnybrook we had over precisely that matter, before we even knew there was going to be another movie?
Allow me to recap the findings: Mike Okuda or Rick Sternbach (or maybe both) pointed out that the image wasn't really fully fleshed out with regard to just what it was we were seeing, and that my offering that what we were seeing was actually a ground test facility, for checking out various prospective systems upgrades could be tested on the ground in nearly real conditions before being sent out to the field, was quite plausible and maybe even likely. And as Rick pointed out recently, Mars gravity is only 0.3 of Earth's. Big fat honking difference.
Besides, we've seen starships, before and after, being put together in orbital spacedocks, including the Enterprise-D. Assembling the Enterprise on the ground is nonsensical in the extreme.
