Nintendo of Japan has registered three new trademarks relating to the Nintendo Wii today: Wii Pointer, Wii Culture and !!M. Although the meaning behind these trademarks are unknown so far, speculation is widespread among Nintendo fans online. The first, Wii Pointer, could very well be a finalized name for the Wii remote, while Wii Culture might be the name of the Wii’s online service that was announced. Finally, !!M, which looks very much like an upside down version of the Wii logo, is theorized to be an instant messaging client due to its striking similarity to the acronym “IM”. Keep in mind that the above are simply rumours and nothing more at this point, but we’ll keep you updated as more information is revealed.
