The developers of Borderlands 4 have started teasing a story expansion. They presented the trailer for Bounty Pack 1: How Rush Saved Mercenary Day
Add-ons from the "Bounty Pack" series are premium DLCs that add "small but interesting story content to the game, as well as new equipment and cosmetic items that can be obtained, as well as a "Vault Card" that allows you to unlock additional loot as you play."
The release of the add-on is scheduled for November 20.
In addition, Gearbox has published a content roadmap: the Horrors of Kairos event should start on October 23, and a free content update is also planned for release this year.
