Nintendo of America, the maker of the insanely popular Nintendo Wii consoles, says the inventory of the game is improving and a good thing too for fans. The Channel Checkers surveyed 32 electronics, game and console stores across the nation this week and asked whether the Nintendo Wiis were in stock, if not, how long before more arrived? The stores included GameStop, EB Games, Blockbuster Video, Toys R Us and Best Buy. Thirteen or 41% of respondents claimed that the Nintendo Wii was not in stock, while 19 or 59% said they stocked the console. Of those who said they did not stock Nintendo Wii, 16 or 50% said they would have the console within one week, 9 respondents or 28% said it would be two weeks and 7 or 22% said it would be four or more weeks before they would stock the product.
