Sony has revealed a new custom PS4, designed with an original PSOne finish, to mark the twentieth anniversary of PlayStation.

The console will be available to pre-order from the US and Europe, priced at $499 and €499, with the supply limited to 12,300 units worldwide.

Packaged in a special commemorative box, the custom PS4 is resplendent with a familiar silver/grey finish, with a small insignia etched onto the chassis that shows each unit's unique number. The DualShock 4 controller, meanwhile, is coloured in the same manner and brings back the original PlayStation logo. A closer look shows that the controller's touch-pad has also been decorated with 20 marked in the pattern.

Pre-orders open on Saturday, December 6, with further details announced at the PlayStation Experience event on Saturday.

Shuhei Yoshida, the president of Sony's game studio division, announced the new console on Wednesday morning to mark a two-decade milestone for the business.

In a note published on the PlayStation Blog, he wrote: "Sony Computer Entertainment, founded by my mentor Ken Kutaragi, was a project borne out of sincere passion and deep admiration for the craft of game development."

Yoshida continued: "The mid ’90s were an exciting time for game developers, driven by the explosion of powerful but affordable 3D graphics rendering hardware and the birth of many young and adventurous development studios. The original PlayStation was meant to embody that sense of adventure and discovery, that sense that anything was possible."
