I haven't seen anything out of the ordinary as far as failure rates go on a new product release. Both XBox and PS4 are well under a 1% failure rate. None of which have been contributed to anything more than poor shipping conditions and dumb'arses breaking them on their own and trying to blame the manufacturer. When I worked for Dell, we replaced optical drives every day for eating disks. It seemed to us there might have been problems because we were the ones replaceing them every day, but compared to the 100 million that went out each year, there was no problem.
