The European Playstation Blog conducted an interview with FFXIII Producer Yoshinori Kitase and the director Motomu Toriyama, mostly consisting of user-submitted questions. Find answers to things like why there isn't a Japanese languae track, is there a New Game + (spoiler: no), and one curveball essentially asking about remaking FFVII.
The US Playstation Blog is set to interview these guys as well with more user questions, so you may want to keep an eye out over there too.
