Sony has already announced intentions to produce a third and fourth "The Amazing Spider-Man" film as well as spin-off movies about "Venom" and "The Sinister Six".
Speaking with Den of Geek, series producer Matt Tolmach has now revealed the timetable for the various films:
"Before we know what we do with Spider-Man 4, we're going to do Sinister Six, Venom and Spider-Man 3. There is going to be a lot of crossover in those movies. So we're just not at Spider-Man 4, because we still have a whole other Spider-Man movie and two other movies. So we don't know yet what [Spider-Man 4] is going to be."
Sony had previously announced a May 4th 2018 release for the fourth Spider-Man film, but that's no longer a certainty - that date will be for a Spider-Man movie in the franchise, which one though is in question.
