Yoshinori Kitase has hinted at a FFXIII 3D release in an interview.
“We don’t know how possible it is to build the game in 3D but we are interested in it,” he said. “In fact, we have already created a 3D Final Fantasy XIII trailer, which is currently showing in Japanese cinemas alongside the film Avatar.”
The game (in 2D, unfortunately!) is due out March 9th for Ps3 and 360.
