AND in new trailer Noct says"It's been a long time coming……almost there"
THAT! that sound like they talk to each other!
"big surprise at the end for the fans"
"For Lightning, her story ends here in Lightning Returns: Final Fantasy XIII, as this game is meant as a finale to this series. But we know that Lightning is an extremely popular character, even when compared to other Final Fantasy characters.So there is a possibility that Lightning would appear in other future Final Fantasy titles, not as a protagonist, but as a guest character."
I wish that big surprise will be Light TUT
