I suspect a color swap is what Nintendo thinks will turn around their diminishing sales numbers, but when this temporary measure fails and PS3 comes out with the Move to push their Sony version of Wii HD, Nintendo will unleash the Wii HD.
Probably next year around this same time. Having a functionally identical White Wii, I'll wait for that HD model. At this point, its inevitable. A Wii with HDMI would be awesome. Though... I say that about all source devices. Haha.
