The Battle Director of FFXIII leaves SQEX

[ShinGundam]

They haven't had an in-house music team since 2009 apparently. It doesn't mean that Masashi Hamauzu can't be contracted to work on FFXIII-2 of course, but he's technically not part of the XIII team anymore since he's freelance now

Huh O_o ????
