I'm gonna say no, but it's possible. It mainly depends on FFXV. Will it sell less than FFXIII? Then splatoon has a pretty good chance. What really is the current state of final fantasy in Japan? We haven't seen a main game since 2009, so it's kind of hard to judge. Lightning returns did terrible though, wow.
