Well, I'm back from the movie now, and my fears weren't realized. The only part where he directly quoted something I recognized from his earlier work was in the POV shot that led to our first look at the full Spider-Man costume, where he borrowed an ascending horn motif he used several times in his Trek scores. Other than that, the music didn't sound overly much like the James Horner style I got sick of hearing in the '80s. He has evolved and broadened as a composer since then. Maybe people who are familiar with his more recent scores would notice more reused elements, but it sounded almost entirely fresh to me. The end title theme does have a Horneresque quality to its melody, but the orchestration is different so it doesn't feel like more of the same to me. I think he is working with different orchestrators these days than he used in the '80s.
