PlayStation 4 hardware teased by Sony hours before next Xbox unveil

Sony has teased shots of the PlayStation 4 hardware hours before Microsoft is due to announce its next-generation Xbox.

The 39-second video shows a blurred black box, which is presumably the PlayStation 4 hardware, along with numerous quick, close-up shots of various parts of the hardware. "See it First at E3," says the video.

Shots in the trailer show close-ups of corners, vents, and a circular edge. The Dual Shock 4 controller can also be seen.

The teaser ends with the time and date of Sony's E3 2013 press conference: June 10 at 18:00 PDT.

Sony announced the PlayStation 4 in February, though the hardware was not shown and Sony said its design was not yet finalised. The next-generation console is due to be released globally later in 2013.
