Originally, the continuation of Michael, Trevor and Franklin's story was set to launch in 2014. However, to this day we are still waiting on any news regarding GTA V single player DLC, and while Rockstar has seemingly shot it down, hope still lingers.

With the story mode of GTA V being as well rounded as it was, you can hardly say that Rockstar left players hanging with no proper conclusion to the plot. In fact, the finale scenes very effectively put a period at the end of it all and there really isn't a lot that can be done. This is because of the open endedness of the game itself, since some outcomes would require the DLC to disregard gameplay features and past events which are at the core of the experience.
