I watched it.... I didn't need to, but I'm not disappointed that I did.
Feige (or someone at Marvel) did say that the trailers will only be cut from items in the first 20/30min of the (3hr?) movie, so no real spoilers to be had.
although i think we just got a glimpse of Kate Bishop in training.
another potential mantle passing for a future Young Avengers or maybe a Disney+ MCU extended series.
anyone know when tickets go on sale?
I need to secure those seats ASAP
edit: there was one tiny minor spoiler, not that we didn't know it would happen, just not that it happens in the first 20/30 minutes of the movie
that Tony and Nebula make it back to Planut Earf. They could've spider-man'd them and removed them from that scene in the trailer like Civil War
