I don't think so. For some reason they like to present flashy futuristic type stuff in trailers, which really isn't my cup of tea as a selling point either, but I'm sure they will have a lot more than this. I could be remembering things a bit off, but I recall as we were leaving the SNES generation Square would show these trailers of Final Fantasy that looked like they had fallen off their rockers. VII's commercial was about some big ass city, with guns, motorcycles, massive explosions and rocket ships. It confused the bloody hell out of me, and the VIII's trailer showed a bunch of armed battle ships heading to a big beach of open gun fire, and made me wonder if the new FF took place on D-Day in WWII.
I'd rather look at something a bit more mystical than a polluted up modern day looking city too, and I'm sure it's in the game, but for whatever reason they chose not to show it off yet. This is the only description about XV's world that I have seen, "The game is set in modern times, but the city-like country Lucis which protagonist Noctis hails from is the only technologically advanced location, otherwise surrounded by medieval nations."
I doubt we will see this game until 2015 though.
