Could the new movie open with Peter Parker at the Avengers tower getting his suit and weapons upgraded?
We know that Robert Downey Jr. will have a role in Spider-Man: Homecoming.
More than likely that moment will happen off-screen and between films, but if we see Spider-Man looking significantly different than he did in Captain America: Civil War we now know specifically why that is.
While the size or importance of the part is not clear at this point, it’s possible that this message may be giving us a clue.
