At PAX East Gearbox Software held a conference which mainly focuses on the studio and its upcoming release, Battleborn. At the 1h:18m mark in the recording a new subject is spoken about, with Gearbox confirming that Borderlands 3 is in development. It is early days yet with art and story still being decided on, which means the game is years away from actually being released.
It isn’t a huge shock that Borderlands 3 is in Gearbox’s plans considering how successful the IP has been. Borderlands, Borderlands 2, and Pre-Sequel have all done well, while a collaboration with Telltale led to Tales From The Borderlands. That is considered one of the best series to come from the studio in recent times.
