Like Grand Theft Auto V, Rockstar's next big open-world adventure, Red Dead Redemption 2, will feature a sprawling online component titled Red Dead Online. The mode will launch as a public beta this fall, and judging by the level of support GTA Online has enjoyed, it will likely receive a regular stream of updates for a long time to come. With a second open-world multiplayer game to support now, fans may wonder if GTA Online's updates will slow down, but Rockstar assures this won't be the case.

In an interview with IGN, Rockstar North director of design Imran Sarwar said the developer still intends to support GTA V's online mode after Red Dead Online arrives. "We still have big plans for Grand Theft Auto Online and we will continue to roll out updates for the foreseeable future," Sarwar said.
