So... let's see what we can figure out about the setting of the film now. First off, the speculation about the trailers taking place in different time periods, based on the intact-vs-shattered moon images, is clearly wrong, because in that last bit we see two moons, one shattered -- which also means this isn't Earth. Plus Ruby, who we assumed was the "oldest" because of the lack of moonshatter in her trailer, appearing at the end of this one, of course -- and being Yang's sister.
I'm sure someone else has noticed, but all the girls' weapons are firearms of some sort (or Nanoha-style cartridge-powered), or seem to incorporate them in some way. But all the girls are also "super" above and beyond their weapons.
What other inferences can be drawn?

Then the horns kicked in...
...and my shoes began to squeak.
