No new details, but a re-affirmation that things are in the works.
GameSpot has run a portion of an interview with Shigeru Miyamoto that ran in the Japanese publication Mainichi, in which Shiggy briefly addresses Nintendo’s online gaming plans. Miyamoto said that the GameCube already has games that are communicating to the player. Elements such as the ability to exchange and share data between the GameCube and the Game Boy Advance and use the Mobile Adapter GB are a means of communication, Miyamoto said.
Shiggy did go on to reiterate that Nintendo is fully planning to introduce online content but echoed what we’ve heard before: only when the market is ready. "There are a large number of online games in development [for the GameCube], which are secret," Miyamoto said, yet did not comment on when those games and the GameCube narrowband and broadband peripherals will be released.
