Variety's report states that this will only be the end of the central Fast and Furious franchise, so it's possible there will still be new side stories in the Fast and Furious universe.
In addition to those eleven core Fast & Furious movies, the series has already produced a spinoff, Hobbs & Shaw, focusing on the characters played in several of the films by Dwayne Johnson and Jason Statham. Just $174 million of that total came from theaters in the US and Canada, underlining just how crucial global grosses have become for this franchise especially. And with the pandemic pushing the release of F9 to May 2021 along with the confirmation of two more movies, it's likely to keep that position for at least the next few years, although Jurassic Park may give it a run for its money.
Johnson debuted in the franchise in Fast Five, returning to star in Fast & Furious 6 and Furious 7, though he feuded quite harshly with Vin Diesel during production.
Fast & Furious is officially driving to the finish line.
It's also possible that F9 new cast members John Cena, Helen Mirren, Cardi B and Reggaeton singer Ozuna could come back for the final two installments. Those would be Fast & Furiouses #10 and 11.
