The CEO of GameStop said as part of an interview with Gamedaily
"I've never seen this type of demand before. I know they're making more, but we're still short like everybody else. I think we'll have a continued shortage this Christmas. I don't see a near-term end in sight for Wii shortages, not unless they really ramp up supply. I think they've ramped it up 20 percent or so, but Nintendo is fairly cautious by nature. They ramped it up 20 and it's still evaporating."
I predicted this same thing back on January 31st of this year. I said Wii resale prices will be above $400 this Christmas season. I stand by my prediction but I don't think the price spike will be as bad as last year's. See the chart below for the 2007 Wii prices.
Wii prices increased almost $200 during November 2007. Right now Wii Console's are selling for $250, the retail price. If the GameStop CEO is right, this is probably the lowest price the Wii Console will be the rest of 2008.
