Any gamers unlucky enough to find themselves with a faulty PS4 should see a replacement arrive pretty quickly.
That’s because Sony is keeping a small number of units in reserve that will be used for those who need an exchange. Not that the company expects many problems – it reckons the PS4 failure rate is roughly the same as is seen with PS3.
"One thing we've done within our stock allocation is make sure we've got a pool of stock to deal with any 'dead on arrival' issues," Sony UK boss Fergal Gara told Eurogamer.
"It's not a vast volume, because there's no evidence to suggest we need a vast volume to deal with that. But our consumer services helpline is there to support gamers and solve any problems that do emerge.
“I don't expect any major issues. Obviously any game who is disappointed is a problem we take seriously. We are looking into causes of those low level problems – and there are certain learnings that have already been taken which means we can potentially further reduce that low level down to as close to zero as we can possibly get it.
"But let's be clear: the failure rate on PS4 is well within the region we see on PS3, which is considered a pretty bullet-proof machine. There is no evidence there to cause panic either for us or for gamers having any lack of confidence in picking up a PS4."
