Aussie-Nintendo.com said:April 16, 2008 - When Mario Kart Wii launches in Australia and New Zealand next Thursday, so too will Club Nintendo, a service that's long been offered to fans in other regions, allowing them to join to redeem points collected from game and hardware purchases for exclusive Nintendo goodies and Wii Points.
The Age's Screenplay blog uncovered Nintendo's plans, thanks to an advance copy of the Australian version of Mario Kart Wii, which includes an invitation to join the club. It'll be available at www.club-nintendo.com, and members will also be able to expect news bulletins and special offers.
