Wii HD (Unofficially) Confirmed?
Despite some people believing that Nintendo can hold off on producing a new system as long as there 
are people in this world who do not own Wiis, there is a recent, and very reliable, rumor that suggests that Nintendo is in fact producing a “Wii HD”. According to the story, Nintendo has been showing off the new system to game developers and publishers, and the set date for this device is in 2011.
While our sources are reluctant to be too specific about “Wii HD,” they have been able to divulge some (albeit predictable) generalizations. High definition visuals are assured, as is a greater emphasis on digitally distributed and backwardly compatible content, indicating that the new system will feature some form of local storage medium such as a hard drive or large flash memory solution. It has also been indicated that Nintendo’s emphasis is again on what the consumer will hold in their hands and interact with, rather than the “console” itself.
This report isn’t just backed up by anonymous sources either, there is another factor pointing at a far more advanced Wii: math. Apparently, the amount that Nintendo has been spending on research and development has grown disproportionately to previous years. The year 2011 will also mark the end of a development agreement between IBM and AMD, who provide core technologies (processors and graphics specifically) for Nintendo.
