Well, I don't think he did. This new trailer for Lightning Returns: Final Fantasy XIII is a little over two minutes. But the last several seconds are what might raise eyebrows. Skip to around 1:50 to see, er, hear what I'm talking about.
While it sounds like Sazh is saying "blasted fuckball", I believe he's actually saying "blasted fluffball" or "blasted fuzzball", But "blasted fuckball" sure is difficult to unhear.
Lightning Returns: Final Fantasy XIII will be out this November in Japan. It will be out next February in the West, blasted fuckballs, I mean fluffballs, and all.
