The consumer electronics industry is no stranger to the concept of hardware shortages. Nintendo is likely only to ramp up production significantly when it anticipates that demand will hold steady; the firm has no intention of being left high and dry with unsold stock. What that means for retailers in the coming months is that once again, consumers are going to face a struggle to get hold of Wii hardware in the run-up to Christmas.
Despite the frustration this will cause, there's no conspiracy here. Neither, however, is there an end in sight. Nintendo will always be happier when its supply is undershooting demand by a small margin - so unless demand for the Wii slumps sharply for some reason, it's unlikely that the channel will ever be fully stocked, and supply woes will continue to some degree. As woes go, however, it seems churlish to complain too much; for Nintendo, and the industry as a whole, it's the best possible problem to have.
