Rockstar Games is set to reveal the first trailer for GTA 6 this December. Recently, a rumor surfaced online about how exactly the developers will be expanding the game with new content. According to the popular dataminer known as Tez2, GTA 6 will most likely be supplemented with episodic extensions. «And it's more of episodic content, aka expansions, than a singular SP DLC. They can do them yearly or biyearly. Which would help reduce crunch», — Tez2 wrote.
Furthermore, he reported that Rockstar Games originally also planned single-player additions for GTA 5 and Red Dead Redemption 2, but because the main efforts went into creating content for online modes, they were never completed.
