Biggerboat is right.
Right now, the increases have been very minimal. In Japan, the Wii has almost always been 70k post-holidays, 90k in NA, and 60k in Europe, with very little changes. DQS might increase the total weekly sales by ~30k units. Thats hardly a difference.
Nintendo would be VERY stupid if they were holding back stores on a system that has complete sellthrough in most locales. Selling them now would allow for more software sales overall. But if they're not finding reasonable strong solutions to produce alot more systems, worldwide supplies of the Wii could be ~500k a week during the holidays, or less, and force consumers to go with the similar priced X360 or the PS3....Which would spell disaster for Nintendo.
So hopefully they are increasing production, in a real, viable way. Brazil would be an interesting locale as well for a factory.
Back from the dead, I'm afraid.
