I'm going to toss out something. As speculated by many fans: Jyn Erso is a play on Jan Ors, While Cassian Andor is a turn on Kyle Katarn. While both are patterns we see the lead characters of the pairs flipped. Also, the guy who plays Cassian Andor (Diego Luna)? Yeah, I dig that his accent is neither American nor British sounding. It's a small thing, but it's a detail that does make the galaxy feel a bit less small (considering how just about everybody over on reddit is trying to make all the characters related, i.e. Rey/Skywalker/Kenobi/Palpatine, or Erso/Poe, etc.)
When the teaser trailer for TFA was dropped, I was ecstatic, but looking back I think it was primarily nostalgia over the Falcon and Solo/Chewie again. With this trailer, I am genuinely excited and cannot wait to see it. I am so excited I am actually pondering going on opening weekend.
