I got to play PDZ for under five minutes before my 360 froze. When/if I turn it back on with or without game inserted I get red lights in sectors 1,3, and 4. I called MS and was told this indicated a hardware failure. After the brilliant tech support told me I should just restart it and call back if it happened again, I was afraid we would get nowhere fast. I then explained that my 360 would not turn back on and was now only a $400 piece of plastic that blinked red lights at me. After some more miscommunication, he said he would schedule a repair man to come out and take a look when I called back with my serial number! Wow, MS does house calls. Before commiting to that though, I called the store where I purchased it and was told that fortunately, someone cancelled their preorder and they had an extra one they had not put out yet. So now for round two, hopefully just one in a million. I did have fun for the five minutes it worked!
