Kotaku has confirmed that Nintendo President Satoru Iwata will announce the long-requested storage solution for the Wii during his keynote speech at the 2009 Game Developers Conference this morning.
Along with the official announcement of Rock N' Roll Climber, a rock climbing game that uses the Wii Balance Board previously leaked by the ESRB ratings website, Iwata will discuss a data storage device for the Wii, which gamers have been clamoring for since the introduction of the Virtual Console with the systems launch.
Rather than a hard disk, it looks like the Wii will utilize high capacity SD solution to solve the console's memory woes.
