Grand Theft Auto 5 technically didn't have any DLC. Grand Theft Auto Online is a separate "free" feature to Grand Theft Auto 5. It wasn't until lately that fans could buy GTA Online separately from GTA 5. But, if we're being honest, you're better off buying the base game if you haven't played it yet.

Having said that, Rockstar has released DLCs before like the ones for GTA 4 and many are well-loved. After skipping it entirely with GTA 5, much to the delight of fans, Rockstar appears to be taking a different approach with GTA 6.
According to Tez2, Rockstar is targeting a holiday 2024 release for the next GTA game. However, this is a date the studio has "pushed back multiple times." The same source is claiming that Rockstar will likely push the game back again to early 2025 but that's it.
Finally, to meet the said deadline, Rockstar is cutting content from the base game and repurposing it as post-launch DLC.
It's unlikely GTA 6 will come out in 2024 or 2025 based on Take-Two Interactive's latest earnings report. Even so, you can trust Rockstar to release incremental updates with new story content that's worth the money.
Case in point, GTA Online. If you need further proof, GTA 4 had some of the best DLCs of its generation. The Ballad of Gay Tony, in particular, was well-loved, and some say it's better than the base game.
Coincidentally, an ever-expanding GTA 6 was rumored last year before the leaks confirmed the game's setting and timeline.
Grand Theft Auto is one of the most profitable video game properties. Rockstar rakes in at least half a million in revenue from GTA Online every year. Not to mention, GTA 5 is the second-best-selling game of all time. As a result, the pressure is on Rockstar to deliver a quality product. To make matters worse, Rockstar needs to make a GTA Online sequel.
All things considered, revealing GTA 6 later this year and releasing it in 2024 is in line with the earlier rumors. It also isn't the worst thing if Rockstar broke up base content into future DLC.
The only question now is, when exactly are we going to see more of GTA 6? Wouldn't it be interesting if Rockstar partnered up with its presumed future owners and made GTA 6 the highlight of the still-unannounced PlayStation Showcase later this year? Maybe this is the plan and what 50 Cent was alluding to before he took his social media posts down.
