Well-known game insider Tom Henderson reports that the development of GTA 6 is progressing very rapidly, and Rockstar Games has no critical problems that can somehow affect the schedule. Thus, the source hopes that the novelty will be released in the time frame proposed by Henderson in the region of 2024-2025.
Note that the authors of the game themselves, although it was officially announced, have not yet told a word about the plot. We were not shown a single graphic material that could be used to make an assumption about the story being prepared for display.
It is worth saying that Tom Henderson is a fairly authoritative source, whose forecasts are almost always confirmed.
The action game also received a content update.
