From a very reliable source ( SKFU ) we have a striking new feature of the PS3 heard. The feature would be present even at the PlayStation Network but is currently still hidden. It is a serial system "which Sony will soon start working. Since the root keys on the street you can see every homebrew tool (including backup management) make it sound like it was made by Sony. This makes it so hard for Sony to gamers with backup managers to detect and block. The idea is that soon every Blu-ray disc, disc with a unique number, comes with a serial key. These 'serial-key then works then only with its Blu-ray disc with matching number. So it will soon be so should work, that when you a game buys and PlayStation 3 do, you activate it with your 'serial-key "and thus a call to Sony to show that you are authorized for that game play on your PlayStation 3.Reportedly, any 'serial-key may be used only five times, as many PlayStation Store downloads. Given the implementation according to our source has already been done in the PlayStation Network, and three unknown input fields on the PlayStation Network, is the probability that this system will be introduced enormous.
