The only 'shortage' that Nintendo creates is a shortage of contracting out more suppliers of the product that goes into and then builds the Wii. Which is because of how conservative N is. First reason would be as you contract out to a wider range, almost by definition quality goes down. But even more important is how deadly afraid N is of oversupply. Thus the supply doesn't jump by leaps and bounds each quarter, but by measured increases every 6 months or so.
Torturing the numbers. Hear them scream.
