Nintendo will reveal details of a "new game product" in spring next year, president Satoru Iwata has told a Japanese news conference while discussing the Kyoto-based firm"s ongoing business strategy.

The fact that Iwata-san has spoken of a "successor to GameCube" in the past and reportedly did not do so on this occasion could be significant.
