Rockstar is certainly not satisfied to rest upon its laurels since it released Max Payne 3, a game that's received both critical acclaim and a whole lot of sales.
The company has since registered trademarks for Rockstar TV and GTA TV. We speculate that the trademarks pertain to Grand Theft Auto V—and planned features for the upcoming game. It wouldn't surprise us if Rockstar added user-recorded videos and other social functions to the Rockstar Social Club, with GTA TV as the service.
We'll be sure to keep you in the loop as we find out more details about what Rockstar has planned.
Grand Theft Auto V does not have a release date, and no platforms have been announced as of yet.
