We know Borderlands 3 will have DLC. Despite a somewhat baffling controversy, it has been confirmed that it will feature both campaign and cosmetic DLC (or microtransactions, for those who are into the semantics of it). However, many have been wondering if it will feature DLC in the form of new Vault Hunters, as the past games have. While the idea wasn?t necessarily shut down, fans probably shouldn?t expect new Vault Hunters to pop up in Borderlands 3. However, you may see the four that are already present gain a few new tricks following launch.
The statement was given by Gearbox CEO Randy Pitchford, who probably knows a thing or two about Borderlands 3?s development (maybe). When asked by a fan if it would feature DLC characters, Pitchford seemed lukewarm on the idea:
We are focused on the main game for now, but my feelings are that it might be better for us to put our time into expanding what the existing vault hunters can do and how interesting their future growth is instead of adding new ones to start over with. Data seems to support this.

Of course, this isn?t completely shutting down the idea. It seems like, at the moment, post-launch plans are up in the air as Gearbox finishes up the game itself. However, if Borderlands 3 doesn?t end up getting DLC characters, it would be a change from the precedent set in Borderlands 2 and Borderlands: The Pre-Sequel, which both got additional post-launch Vault Hunters.
Howeve...
