Shigeru Miyamoto told me during an E3 interview that he's working on a new game of his own, when his other job of being a very important executive allows it.

"One thing I want to clear up," Miyamoto told Joystiq, "people like to ask me if I want to do a small project with a small team. I do like working with a small team, and I'm working with a number of small teams on a lot of different ideas, but the problem is because of all these different roles that I have to fulfill, it takes me a long time to write the design document." In addition, working with small teams causes design work to take longer, he said, so "maybe this time next year I'll have something ready to show you that perhaps will illustrate that idea."

Miyamoto confirmed directly that he's working on design documents right now. "I have some storyboards that I have to draw before I finish this trip," he added. "It's fun. I useFlipnote Studio to draw my storyboards."
