During the 13th Annual Japan Media Arts Festival, Shigeru Miyamoto not only won an award, but also spoke about some inspirations for Super Mario Galaxy and also some interesting news of a new MotionPlus game he is working on. He also confirmed that new Nintendo hardware is in development.
During the event, Shigeru Miyamoto received a Special Achievement Award, presented to him by the Agency of Cultural Affairs. He was also joined by Square-Enix executive producer, Akitoshi Kawazu, who was heading the panel selecting exhibits for the festival's Entertainment category. More interestingly though, Shigeru Miyamoto spoke about an experience involving a hamster, which inspired part of Super Mario Galaxy.
Before the development of the game, Shigeu Miyamoto revealed the idea for it came from a hamster he was caring for in his house. At the time of development of the game, he was faced with complication with 3D control and wanted Mario to run freely like a hamster. The game was set on spheres with gravity on a set point and was designed that way so anyone could play. It allowed players to run around pointlessly and return to the same point.
Shigeru Miyamoto apparently revealed that he is also working on a new MotionPlus based game. Unfortunately, he didn't reveal any details on it. Furthermore, He confirmed that new hardware is in development, but again, no details were talked about.
