1. It Will Lead Right Into Spider-Man: Far From Home
Spidey's death in Avengers: Infinity War is unlikely to stick, and we know that because Spider-Man: Far From Home is scheduled for release in the summer of 2019 and Tom Holland's friendly neighbourhood wall-crawler is set to return.
Given that little is known about Marvel Studio's Phase 4 plans, firm details about the Homecoming sequel are thin on the ground, though it has been confirmed that Peter's next solo outing will pick up just minutes on from Avengers 4's conclusion.
This intel comes from a credible source: Homecoming producer Amy Pascal, who spilled the beans to Fandom last summer.
"What I think we should focus on is this Spider-Man who started in Civil War and then has this movie, and then will be in [Infinity War], and we are starting now the next one which will start a few minutes after Avengers 4 wraps as a story."
This is almost official confirmation that Spidey will be resurrected by the end of Avengers 4, although there's always a chance Far From Home will take place in a parallel universe or alternate reality, as they're very much a thing in Marvel lore.
One thing is for sure, as the first movie in the fourth phase of the Marvel Cinematic Universe, Far From Home will mark a new beginning for the franchise. Marvel has alluded to that much on more than one occasion, but whether that means Avengers 4 will perform a hard reset of the series' timeline remains to be seen.
