I was told at two Dayton, Ohio area Best Buys that they would have Wiis on 12/17. Two different people on different days at each store told me this, and one at each store told me that they would be in the ad that week.
Also, the Funcoland (EB games) in the Dayton Mall upstairs has received shipments of consoles two days in a row around noon and sold out in minutes. They wouldn't tell me how many they received. they also had about 10-12 classic controllers at 3 pm today.
