Even if this isn't an outright announcement, the choice of character and words implies that Rockstar will continue expanding the existing game world rather than rushing towards the next installment. If the current online infrastructure continues for several more years as suggested, players can expect continued support and new content for the existing platform. This means more updates, more events, and more additions to Los Santos.
This begs the question, when is the sequel to GTA Online coming out? Previously, GTA Online was made available through Grand Theft Auto V less than a month after the single-player component's release. However, it wasn't after several updates that GTA Online really took off. Perhaps Rockstar wants to avoid that rocky start by making sure that everything is in order first.
Either that, or Rockstar would prefer to launch the next GTA Online in front of as many eyes as possible, which may not be until 2028 when GTA 6 will be available to play on this current generation of consoles and the next one as well as PC. For now, players will need to find satisfaction in the ongoing adventures within GTA V and GTA Online. But if it's any consolation, the message from Rockstar seems clear: they're clearly aware fans are watching and waiting.
In other GTA news, Take-Two is expected to reveal more about the franchise's sixth mainline installment within the next month ahead of its next earnings call. Also, this rapper claims that one of his viral songs will be in GTA 6.
