This story contains major spoilers for Spider-Man: Brand New Day. It's possible Holland was busy making Brand New Day and Christopher Nolan's The Odyssey at the same time—which seems like a fair excuse. But it's also possible Marvel is saving him for their big 2027 tentpole, Avengers: Secret Wars. This has been the prevailing fan theory for a while, but the Brand New Day post-credits scene backs it up. And we'd bet on Secret Wars.
