Nintendo's tried-and-true strategy for jolting hardware sales that aren't white hot (aside from bullshit shortages) is to toss a new color into the mix. And it works! Today's color is metallic silver, like the original DS, but shinier. Ooo, shiny. [Kotaku]
If we go buy "BS shortages" for the Wii and the color ratio, then god Nintendo MUST be telling the truth, otherwise we'd have gotten different colored Wiis already.
Nintendo only colorizes when they need you to buy yet another of the same system with just a cosmetic color change to match your sneaks and new era cap.
From this data, I thus make it known that the Wii is really so damned hot that Nintendo doesn't need to add a color into the mixer...yet. Maybe in a few years when NIntendo isn't printing money?
