Regarding how Inafune's departure came about, Capcom said: "With the harshness of the current market, we felt that there was the need for some fundamental reforms to the development structure. During the preparation phase for these structural reforms, Mr. Inafune had desires for where he'd like to progress as a creator, and as a company we accepted this, resulting in the announcement."
In statements shared at last week's financial briefing (click here for a Japanese PDF), Chairman and CEO Kenzo Tsujimoto listed Katsuhiko Ichii as Capcom's newly appointed head of development.
Capcom has made Inafune's departure completely official, removing him from its corporate officer page.
Inafune's title was "Head of R&D Management Group and Consumer Games R&D Division and Contents Management Division." At the corporate officer's page, Nobuyuki Matsushima is now listed as Head of Consumer Games R&D Division. He was previously Deputy Head of Consumer Games R&D Division. Ichii is listed as "Head of Consumer Entertainment Business Management Group and R&D Management Group." He was previously "Head of Consumer Entertainment Business Management Group and Consumer Games Business Division."
Resident Evil 5 producer Jun Takeuchi has also been placed on the corporate officers list. Takeuchi is listed as "Deputy Head of Consumer Games R&D Division and General Manager of R&D Production Department"
