1. Frank Sinatra playing during the trailer.
2. NCR flag next to ominous looking character.
3. Pip-Boy on ominous character's left wrist.
4. A7 on the back of the character's coat.
5. [7] on the left side of the character's helmet.
6. Strange apparatus on character's back below A7.
7. Some unidentifiable text on the back of character's helmet just above a small, finger sized hole or slit. Probably nothing.
8. Face gear on character.
9. New Vegas, possible structural landmarks (such as the tower with a disc at top).
10. What looks like a tunnel on the far left of the city-scape, at mountain base.
11. Complex on far right of city, shorter buildings, fewer lights.
My speculations
1. This was possibly used in order to give us a sense and feel of what the design of New Vegas is based on. The air and feel of Vegas during the Rat Pack period. Likely safe to say there will be rat pack references aplently in the game.
**2.I need more time to research the NCR before properly forming an opinion.
3. This points to either vault origins of the PC, or the PC having vault interactions early on. (possible ways of getting pipboy could be thievery, murder, bartering, or even integration into the society.
4. I can only guess that this relates to the character's unit/team/sectional/regional breakdown within the NCR.
5. see number 4.
6. kinda looks power armor-ish. Quite possibly a re-breather of some sort with some connection with the facemask.
7. Likely means nothing, if someone has the capability of enhancing it, it may be a hidden tidbit.
8. Yes we all know it looks like a helghast. But in all seriousness it looks alittle high-end, and together with the apparatus on the character's back, it gives me the impression of a Power Armor////Combat Armor Hybrid. Heavy looking shoulder plates and shiny black leather looking boots add to the effect.
9. I don't know much about Vegas, at all. But there may be some structures persisting between the real and game worlds.
10. Looks large enough to possibly be a train tunnel, likely connecting to or formerly connecting to the next major settlement/city. Or what was the next large settlement/city.
11. Could be any number of facilities such as water purification, waste management (imagine the references!), or power related. Or it could even be a downtown slum or second class citizen type area.
Please feel free to add any details you noticed in the trailer that I may have missed, and I will add them to the original list of details. And by all means speculate to your heart's desire, or offer your opinions on mine. All relevant interactions welcome!
Regarding number 9, The Fishy Wanderer suggests this may be the real world equivalent of the tower seen in the trailer. http://www.arrivelasvegas.com/sp/Stratosphere_2.jpg
