Anticipation couldn't be higher for the next game in the Grand Theft Auto franchise. The success of Grand Theft Auto Online has driven sales of Grand Theft Auto 5 for over eight years, but there's a clearly a hunger for what Rockstar's working on next. For now, Rockstar is remaining silent on Grand Theft Auto 6, but it's just a matter of time before an announcement is made. Fans may want to hope that's some time away, however, as one insider is warning that Grand Theft Auto 6 may need more time than Rockstar has.
