Then he went and checked with XBox support if the email was real!
Checking my e-mail earlier today, I found a rather interesting message from Xbox Customer Support, saying that a software update is stopping some Xbox 360s from reading game discs.Saying they were able to detect this issue over Xbox Live, Microsoft went on to say that, after jumping through all the necessary hoops, they'd send me a brand new Xbox 360 S and a year's free Xbox Live. At this point, my jaw hit the floor.
Microsoft Europe is now pointing affected users to the support page to get sorted out. One way or another, affected owners can expect to be mollified by getting their Xbox 360s replaced with new 250GB Xbox 360S
