Well to be honest I don't look that often as I'm not a happy to go shopping type. But I will say this much at least. I tend to buy 1-2 games a month, and I poke into game/dvd new/resale, retail that have stuff like that, and others on at the least once a week. Outside of twice since launch when I've just wondered in at the right time to see someone sliding a credit card for a Wii I've NEVER seen one sitting on a shelf collecting dust...ever.
I live in the 14th largest metro city area in the states and we have a shit ton of stupid Gamestops, multiple Targets, a few Walmarts, places like Meijer, Circuit City, Best Buy, FYE, and others...never seen them. I see a smaller than other parts supply but always some in stock of both controller parts, and an abundance of games, but that damn console is always sold out.
I can only imagine those upset and longing for them do a good amount of call campaigning on Tuesday mornings when those weekly shipments arrive and just take an hour/day/half day off work and just go and stand around until the truck arrives sometime in the morning to get one. I know there also used to be those 'Find a Wii' tracker sites that hit on Target and a few others and gave location, shipment totals, and # in stock too...those still around?
