This release window makes sense for the project given that, as the site points out, Affleck will write, direct, and star in his next directorial effort Live By Night in the summer of 2015. That film will debut October 7, 2016 and frees up a lot of time for the studio to develop the script and get production going. There is also the possibility that Affleck could direct the project, but don't expect any reveals or confirmation for some time.
