In a recent update of his online diary, Nobuo Uematsu mentioned some details concerning his upcoming significance in Final Fantasy XII's soundtrack. While not being the sole composer involved, he does say he wants to "try something new" and talks about his love for a variety of Japanese music. Didn't we see that in Final Fantasy X already?
