Although Rockstar Games has yet to confirm new expansion content for its current "Grand Theft Auto" franchise, speculations suggest that a biker-themed DLC pack is to launch soon for its online multiplayer feature.

Rumors suggest that based on data mined by players, the recent DLC released for "GTA Online" contains some interesting scripts that hint on future releases. Reportedly, some of the files behind the new "Cunning Stunts" DLC point out a biker-themed expansion in the future. These files describe biker-themed content with the "gb" prefix. For example, the scripts list a "gb_biker_joust" line, which may relate to a contest between biker gangs.

The "gb" prefix has been used by Rockstar Games development team as information for CEO or VIP mission in previous DLCs like "Executives and Other Criminals" and "Further Adventures in Finance and Felony."

In addition, the scripts list also has an added "am_mp_personal_mod_garage" line, which may mean that players can get biker-themed properties like a bike-only garage with customization options.

A new DLC centered on biker gangs is highly possible in "GTA Online." Prior to "Cunning Stunts," previous expansion content introduces players to build their own criminal organizations, and even hire other players to act as bodyguards.

Meanwhile, aside from a new biker-themed DLC, Rockstar Games may be planning some major updates for the entire "Grand Theft Auto V" game, including the single player campaign. According to Express, major releases are still planned for "GTA V" until spring next year. This means that in addition to the rumored "Biker" DLC, fans may also get to see the much-anticipated "Online Casino" expansion content for the online multiplayer. A casino-themed DLC is rumored to come out for "GTA Online," since Rockstar Games has previously hinted that some of the assets in the title point to in-game gambling and casino gaming.
