I finished Metroid Prime 2 (again) the other day on the Wii U and noticed in the credits that Tatsumi Kimishima is credited in the Special Thanks. Apparently he is credited in Prime 1,2,3 and Fusion, Zero Mission too. Sometimes the credit is under the NOA section. He's credited in a lot of Gamecube era games but most of the times in the Metroid Special Thanks he is mentioned first.
Maybe he used to work closer with NOA back then, but hopefully the new president (Kimishima) feels that a new Metroid is warranted and wanted.
