Considering how poorly Lightning Returns did in sales, and the sequels in general, I doubt it. I even see fans of FFXIII burnt out on XIII. They just want XV and KH3 to come out. They'll probably just keep it alive through books and have Lightning continue to guest star in other games for a while. I think they were serious about Lightning Returns being the last one, but I'm never surprised to see a sequel after the fact. Alien 3 was supposed to be the last Alien movie, too >.>
