What really confuses me are the attach rates for the 360.
If we assume that all the 360s sold are in unique homes -- and none are redundant consoles because of breakages -- then the attach rate is superbly high. Suspiciously high, even, at 8+ games per console.
Now, what happens if we have significant redundancy? The attach rate goes up, and up to monumental levels. If 30 percent of consoles are replacements, then the attach rate is well over 10 games per console. Given that the attach rates are already extremely high for the 360, this quickly approaches absurdity.
More than anything else, this suggests to me that the failure rates probably aren't that high.
