They could just be pulling our leg here but it does seems like the actor for Franklin is teasing us about an upcoming story-based DLC. There have long been rumors that Rockstar will be working on a few story base DLC for the single-player mode of the game.
So far, the only DLC we have gotten were for the online multiplayer mode. Rumors about a story base DLC on its way started after some fans reported that they found some files in the framework that indicated that a few story base DLC will be available in the future. It was later added that some of the DLC might arrive as paid DLC.
This week, the actor for Franklin, Shawn Fonteno posted on a picture of him wearing a motion capture suit relaxing at Rockstar on Instagram which many fans are now saying is an indication that he is working on a new DLC with Rockstar.
However, there is also the possibility that the image was taken way back when he was working on the game and was only release now to confuse the fans. What do you think?
