While pre-orders are still very much available, at the time of writing, around Europe and elsewhere, it seems that demand for Wii U in the U.S. is hitting some impressive heights. We previously reported that Wii U pre-orders were selling out in the U.S., in terms of online purchases, but it's now being reported by softpedia.com that major retailer GameStop has completely stopped Wii U pre-orders.
An alternative is being offered to members of the PowerUp Rewards loyalty program, in that they can be placed on a waiting list — without a deposit — and they'll be contacted with an update when the system launches on 18th November. Being on the waiting list is no guarantee and it seems likely that those without a pre-order will be unable, waiting list or not, to get a system on launch day.
We haven't yet seen reports of sales on this level in other territories, with retailers still accepting pre-orders; the U.S. is undoubtedly in love with Wii U, however, which is sure to make Reggie Fils-Aime and his colleagues smile.
