It sounds like Nintendo has realised that they need to adjust their business practices to bring in best practices from various places. So they've looked at Western business structure and decided to adopt elements of that.
And Reggie and Shibata becoming "executive officers" suggests to me that they're trying to expand their Western business itself. It will probably result in NoA and NoE having more ability to influence development, especially outside of Japan.
