With only days until launch, Square Enix is promoting Final Fantasy XIII heavily now. There’s even a documentary about the game, which has making of footage and a peek inside Square Enix’s headquarters.
It’s all in Japanese so the developer, singer, and voice actor interviews might not mean much. You can skip videos 1-3 and go straight to the production video. Videos 5-6 have hosts Ai from Morning Musume jumping into battles and Masashi Ebara, the voice of Sazh, playing with Lightning in horse riding mode.
