Actually look at the source, its Gameinformer or the rag of the used game game/console bonanza which is Gamestop!
What kind of consoles do people tend to trade in at somewhere like Gamestop? Unreliable, dying consoles which cannot be sold anywhere else? Yep. if there were no problems you probably wouldn't trade in there because you'd either sell it for more money elsewhere or you would keep it.
What kind of consoles are people who buy from gamestop more likely to be? Used or launch models, or both. Its either the hardcore, get in there first market or the cheapass get it cheaper market. Either way you're looking at a disproportionate number of unreliable consoles in that market compared to anywhere else.
What else is important? The Xbox 360 console has been on the market for a year longer than the PS3 and Wii, the former of those got out of the gate slower so the average time of ownership is markedly different as the PS3 really didn't take off in the U.S. until the price cut. Theres simply been more time for 360s to fail.
Tease.
