Anyone ever actually seen one of these discs? They were apparently shipped with pre-launch retail kiosk systems:
My theory is that they hadn't finished the final system menu software when they manufactured those units, so they shipped them with a stub that only had enough code to display that "Please Insert the Wii Startup Disc" screen, and install any updates off a disc you inserted, but I'd love to get some confirmation of that and see what was actually on the disc.
It looks like a few of these actually leaked out to customers, e.g. here. There used to be something on Nintendo's tech support site that said something to the effect of "If you ever see this message call us IMMEDIATELY", but I can't find it anymore. :(
