Gearbox looks to be hiring a writer for Borderlands 3, and while we can't explicitly confirm that's what's happening, the writing seems to be on the wall. Check out this job description and continue on below:
"Gearbox is looking for someone to join the writing team for an unannounced AAA FPS/RPG hybrid with strong characters and central narrative thread.
The successful candidate will join the writing team to write, punch up and iterate scripts in-line with established story and plot outlines. Responsibilities will include writing dialogue for voice-over and in-game text for missions, flavor and user interfaces. A love for comedy writing with respect for a serious underlying plot is helpful."
Now, it could be that Gearbox is working on a completely new ip separate from the Borderlands universe, but we all saw how that went with Battleborn, and it doesn't seem like good business to strike new territory when you have a great franchise sitting in the bullpen ready to go in.
There's also the fact that Gearbox has explicitly said they're dedicating about 90% of their staff to "the game we want them to work on". Let's just hope they get someone for the job sooner than later otherwise the world will begin to forget what a great franchise this is!
