With the announcement that Nintendo's upcoming DSi handheld
will have access to downloadable games came the redubbing of Wii Points to the system-agnostic Nintendo Points -- but reports suggest the two platforms will retain their own payment systems.
According to diagrams published by Siliconera
, prepaid point card will be branded with both the Wii and Nintendo DS logos. Once activated on a particular system, however, the points become platform-specific Wii Points or Nintendo DS points, and can only be used in their respective marketplaces.
Presumably, that method holds for points purchased directly through the marketplaces using a credit card.
As Siliconera suggests, the limitation is likely the result of Nintendo's lack of a cross-platform online account system for users. By contrast, Microsoft's digital distribution system features a point-based payment system that is portable across Xbox Live, Games for Windows Live, and Zune.
Nintendo will release DSi on November 1 in Japan, with a North American release expected in mid-2009.
