The first date is probably reserved for Morbius, the next Spider-Man spinoff on the docket, while the sequel is practically guaranteed to be Venom 2.

According to Variety, an “untitled Sony-Marvel project” will be released on July 10, 2020, and an “untitled Sony-Marvel sequel” will follow on October 2 of the same year.
