SONY has released a teaser trailer hinting at the form of the upcoming PS4, in an attempt to steal away the focus from Microsoft.

The Redmond firm is today due to unveil the replacement console for the XBox 360.

However, Sony yesterday released a brief video clip featuring blurry close ups of the PS4.

While the PS4 was announced back in February, only the controller was shown to the public, along with brief samples of some key titles planned for the platform.

Microsoft will unveil their new console this evening, at 6pm UK time, although it is expected to have similar specifications to Sony's next generation device.
