The latest update from the underground Sony PlayStation 3 scene puts a mysteriously unreleased PS3 firmware into the spotlight. Firmware version 2.16, just one minor spot shy from the latest version of Sony's next generation console software, was allegedly found to exist in PAL versions of Polyphony Digital's Gran Turismo 5: Prologue.
This development came after the fact that many have pondered over the significance of firmware 2.17. It was said that 2.17 came with complementary network code for GT 5 Prologue, though tangible evidence wasn't provided at the time.
