According to what I'm hearing here and over at TrekMovie, the Big E's being built on earth. Nothing to say that the major components were not built on the ground and then hauled up into space for final assembly.
The render is awsome and it looks like the still was from the very end of the trailer during the pullback/reveil. Looks like they're vamping on the TMP version of the ship over the 60's TV version. As I said in the other thread, this looks a good deal like Gabe's version of the Big E, right down to the warp engines. I'm liking what I see so far but,..... I need more pictures!
