From reading comments on the Amazon website, it was available for order beginning sometime last Friday, Sept 15. Having sold out all pre-orders the same day, this would seem to indicate a tremendous pent up demand for these devices. Some actually bought more than one!
Here is a comment from one customer that made it under the wire: "Amazon offered preorders with Wii Sports included for $249 today. With 1 day expedited shipping ran $283.83. No absurd bundle required. They began taking preorders this morning and had sold out of preorders by 11AM CST.
