Marvel’s Spider-Man 2 went ahead and basically carved out a roadmap for a potential half-sequel or full-sequel to follow, including yet another tease of Green Goblin with Norman distraught and his son in a comatose or sedated state. Indeed, Marvel’s Spider-Man teased Green Goblin fairly explicitly back in 2018 and that still has not been fulfilled yet in the series, making him a shoo-in for Marvel’s Spider-Man 3 now as one of a few villains that Marvel’s Spider-Man 2 leaves a trail of blatant breadcrumbs for.
