The Latest Iwata Asks: Fire Emblem Awakening refers to Genki Yokota and Hitoshi Yamagami as members of "Software Planning & Production Department".
It could be a mistranslation, but i don't think it is. It looks like Software Planning & Development Department and Software Planning & Production Department may have gone independent of each other. This separates the SPD that develops games (Sakamoto's boys) and the ones that mainly plan and produce (Tanabe and Yamagami).
Lots of R&D changes being revealed as expected.
