Nintendo of America prez Reggie Fils-Aime spoke on the subject in a recent interview with The Hub.
"Nintendo manufactured, through the end of December, four million units worldwide. And to put this in perspective, the ramp up you need to have from a manufacturing standpoint to make four million units, and to make them flawlessly -- our defect rate is miniscule -- that's a huge challenge. Yet, because of the demand, because of the buzz, we could not satisfy consumers worldwide.
We work with our retailers to supply them on a regular and ongoing basis. Some retailers make decisions to hold product to support their circulars that typically drop on Sundays. But I'm now looking at a report that says in 93 percent of retail outlets, there are less than three hardware units available. That is a huge issue and something we're working very hard to fix."
