Interesting response—or non-response, as it is—by the voice of Franklin in Grand Theft Auto V at a New York Comic Con 2013 panel. When he and his co-stars were asked which Grand Theft Auto character they wish they could have portrayed, Fonteno replied Carl Johnson—the protagonist of 2004's Grand Theft Auto: San Andreas.
According to IGN (the host of the panel), Fonteno added that he's not disappointed that he missed out on playing C.J. because he's currently working on a project with Young Malay—C.J.'s voice. "When [moderator] Greg [Miller] pressed him on what that might be, Fonteno dodged the question and quickly changed the subject," reports IGN.
The Los Santos of Grand Theft Auto V has homages to the city C.J. came to rule a decade ago, including this cameo by three members of the Grove Street Families, riding bikes. Whether C.J. and his friends are returning at some point—he'd be in his 40s in this continuity—it's notable that two voices of Grand Theft Auto's west coast protagonists are teaming up for something.
