It turns out that desire for higher-definition visuals is much higher than Nintendo expected. Those Wii component cables that showed up on Nintendo's official online store have completely sold out. In addition, GameStop's online listing has been pushed back from December 5 to the 15th. If you're impatient, however, you can purportedly still purchase MadCatz's "HD Premium" component cables for $60 as of December 1.
Has Nintendo underestimated the expedience at which consumers have adopted HD (or, at least, ED)? A 480p screen isn't a head-turner, but it certainly beats standard definition. Looks like the House that Mario Built might have to add more detail into the plumber's mustache sooner than they expected.
