Isn't Mikami's protege game designer directing this? I forgot her name. That's probably what the leak stating "Mikami is not involved" is about....I take that as possibly not in the directing role.
Anyways, I'm interested to see what this young up and coming director can do.
Mikami said that there are three Tango members he thinks could direct a game, Ikumi Nakamura, Shigenori Nishikawa (Madworld's director) and Naoki Katakai.

I think he chose Nakamura.
