Tycho says it best

"360 failures always spike when a game worth playing comes out, which (to me) seems to imply that most of the three-sixties installed in homes currently are used as decoration. You'll recall that it happened with Forza 2 and the sequel to Guitar Hero, as well. It's incredible that we are in a situation where every time a worthwhile game sees release, it sweeps through the entire userbase with a scythe. Literally incredible, as in, I can't fucking believe it. It's like flipping a coin, and every time it comes up heads four hundred dollars catches on fire."

Just an FYI, $400 on fire goes up like flashpaper.
