Deadline reports that Sony is developing a second Ghostbusters film on the heels of the all-female version announced a few weeks back. Early details point to both movies taking place in the same world, much like the Marvel Cinematic Universe films. Joe and Anthony Russo, who most recently directed Captain America: The Winter Soldier, have been tapped for the male version. Channing Tatum is rumored to star, and original creators Ivan Reitman and Dan Aykroyd may produce.
This means we may have a Ghostbusters Cinematic Universe, with different cities having their own team of Busters. Time will tell if the franchise has enough legs to last multiple films.
