Thank you Hurmoth for posting this in BPN.
Feeling it should match what Sony and Nintendo offer, Microsoft extended the Xbox 360s warranty from 90 days to one year in the United States and Canada. Anyone who bought an Xbox 360 in the two neighboring countries and paid for repairs will receive a check sometime after they are sent out (beginning 10 weeks from now). This move by Microsoft is also thanks to an online petition, with 3382 signatures as of Friday, seeking the warranty extension. Jeff Bell, marketing vice president at Microsoft, reminded Xbox 360 users that "customer satisfaction is a central focus and priority for the Xbox 360 system."
