I reject nuTrek and substitute my own Trek reality. In my Trek reality, there are Loknar, Nelson, Hermes, etc ships, most of which were built in the 2240s, upgraded in the 2270s, and the alt TNG uniforms I designed were used by Starfleet from the 2360s to at least the 2390s or so. The TOS timeline is slightly different, using episode ideas from Alternatehistory.com's timeline "That Wacky Redhead."
There's a LOT of Trek guys on staff there.....I would not be surprised if there's a good bit of misdirection in that promo....they KNOW people are going to dissect every little detail. So why not throw some herrings in there to watch us go batshit crazy over. I would if I were them.
There's a lot of green on the floor in the foreground of that fuzzy set picture, which is unlikely to be accidental on a film set. This could be the bridge of a ship or it could be another work area, like the engineering deck, that will use digital set extensions.
That green in the foreground could be a situation table, like the one at the rear of the NX-01 bridge or in the Enterprise-D's engine room. Effects of some kind could be added to it in post-production.
Sulu wore a blue shirt with the spiral insignia in "Where No Man has Gone Before." So did Dehner and the other blue shirts. http://tos.trekcore.com/hd/albums/1x03hd/wherenomanhasgonebeforehd065.jpg http://tos.trekcore.com/hd/albums/1x03hd/wherenomanhasgonebeforehd368.jpg As you can see in both images, Scotty wore the sphere-with-the-equator (planet symbol?) insignia with his tan shirt.
Is the collar symmetrical? We can only see one half of it. I had no idea! How can that be explained away?
Explained away? How about incorporated. The standard for the Pilot uniforms need not follow the same for the mains series, seeing as they are different uniforms.
Actually, I experimented with the idea that the "contradicting" options reflected a different combinations of skills/specialisms (for instance, Command was available in Command-Command or Command-Engineering, which might for instance designate Line Officers and Helm/Nav/Weapons respectively).
The initial footage of the ship, despite crude or not, was cruising away of its shipyards, so considering this is a, probably, brand new ship at the time of the series, it might have an official christening, or whatnot ceremony. So, dress uniform for the 1st/pilot episode or portion of it, would make sense to me. But it all has to do with the story and other elements we're still not aware of. So too early to tell and it does also give me the feeling of Cage's field/Landing Party Jackets. Unless, the plot has something to do with time travelling, the Shenzou is a post Voyager ship and this uniform is really Shenzou's era uniform(in a scenario were it travels back in time to correct a timeline that has been polluted by Klingons getting Cloaking tech early or something, which I got inspired by this user that claimed owning internal info about the plot the other day. The Sarcophagus details reminded me of how in STO there is a Klingon faction that retained info about the future from their dealing with the Na'kuhl. Maybe they aproached them in an earlier time period, or stole a cloaking device and stored it were nobody would think of searching, in a sarcophagus ship. Yet section 31 steals it and is hunted by Klingons to get it back. If all this is at all credible and not a wild speculation on my behalf{and at this point it is, so I think I'll go with my first paragraph for the moment}).
Well, technically, the 'pajama' uniforms from ST:TMP came and went fast. But again, maybe the ST D uniforms have been in use a while; and the turtleneck style shown in TOS: "The Cage" was brand spanking new - and lasted 11 years - and were phased out right after the events in TOS: "Where No Man Has Gone Before".
Which is funny because director Robert Wise said this about TOS: "I insisted on changing the costumes as soon as I came in on the project. The originals look like pajamas or something." I do like some of the TMP but they look a LOT more like pajamas than the TOS shirt and pants!
