Almost a million for brawl in a week. I don't think this will be the proving ground naysayers were looking for in that hardcore titles do not sell on Wii.

 Shortage of parts is possible, production glitches, not enough stock to ship out because of the air shipping earlier, so many possible reasons

Shortage of parts, production glitches, air shipping?

After Nintendo successfully delivered how many million units successfully into the hands of consumers during the holiday season?

I'm finding it pretty hard to believe they're running into logistical problems well after establishing their current production infrastructure. If anyone believes this, I don't see how they can simultaneously be forecasting significant increases in production later this quarter if the current rate of production is in reality maxed out at about 1.5min per month.  It's putting the cart before the horse here if the numbers are accurate. Firmly establish that 1.8min per month Nintendo claims first.

Air shipping? One of their primary production facilities is located right in Japan. Most going to the Tokyo metropolitan area where they're being sold. They have another in South Bend, Washington to handle U.S. production. Facility sizes and employment numbers of each facility are protected as trade secrets, but if anyone can shed a little light on this apparent discrepancy, it might explain The Case of the Missing Wii consoles.

You can't airship* every month. Holidays were special and stole some of the next month inventory, on top of stock piling they've got.

Smash is a lot bigger in NA and they probably will need to stock pile for March 9, too. Since, we haven't got any news on when they'll ram up their money printing machines.

* rushed shipping that cost them more to push inventory to stores faster. Be it air, ship, or spaceship...
