Maybe Iwata knows what he's talking about.
According to a story at Nikkei Net, conveniently translated by the fine folks at Video-fenky, the gaming market in Japan is getting smaller. Console sales have dropped off dramatically as most of the people who want current systems have already bought them, and game sales are down too. The overall market is down for the third year in a row, with sales declining 11% in just the last year.
These numbers seem to validate Nintendo President Satoru Iwata's many remarks upon the failing game business in Japan. Iwata thinks the best way to revitalize his country's interest in gaming is to introduce new ways of playing, which Nintendo plans to do with its DS handheld system and the mysterious successor to GameCube.
