In the latest issue of Official Nintendo Magazine Shigeru Miyamoto has discussed his evolving role at the company saying that other producers have stepped up but that "final responsibility" still rests with him.
In the interview, picked up on by Nintendo Life, Miyamoto says:
"As you saw at our presentation at E3, Mr Aonuma chased me off stage… he doesn’t need me any more! The final responsibility for the title still comes down to me and I’m still involved in the games, but I’m definitely able to leave the series up to him in a way.
"… I don’t have to look at every minute detail of every game any more. I know there’s going to be the level of quality that we expect under his supervision.
"Similarly we have Koizumi-san, who’s the producer or the Mario series and it’s the same type of situation. And certainly Konno-san with Mario Kart, too. And Mr Eguchi, producer of the Animal Crossing series. These are the main producers that we’ve trained who are talented enough and we can allow them to oversee the project and manage all the details and still maintain the Nintendo level of quality."
While recent Nintendo games such as Animal Crossing: New Leaf have been received well it does seem that the company is making the necessary arrangements for Miyamoto's eventual retirement.
Despite this, Miyamoto hinted in July that he is working on a new franchise.
