The Homecoming footage shown at San Diego Comic-Con 2016 focused more on Peter’s day-to-day experiences in high school, rather than his superhero activities on the side.
Still, the trailer should at least include the web wings footage that was shown at CCXP.
Peter Parker’s Spider-Man has been armed with “web wings” in comic books past, allowing him to sail through the air (much like a base jumper does) when he’s not swinging from building to building.
It seems unlikely that the Homecoming trailer attached to Rogue One will show off too much of either Spidey and/or his enemies’ tech in the film, based on the expectation that it’s just a teaser.
