The PlayStation 4 would be a long-awaited successor to the 3, launched in Europe in 2007.
The hotly-anticipated PlayStation 4 is expected to be unveiled tonight.
Electronics giant Sony is holding an event in New York, during which it promised to reveal “the future”.
But the games manufacturer has refused to confirm widespread rumours that the latest version of the console will be launched.
Leaked photographs which have emerged online appear to show a prototype controller with a touchpad alongside the classic DualShock-style controls have fuelled the speculation.
The unveiling will excite millions of computer games fans across the world, and further fuel the ongoing battle between Sony, Xbox 360 manufacturers Microsoft and Nintendo, the makers of the Wii system.
Since the first PlayStation console launched in December 1994, Sony have sold over 310 million home consoles worldwide, and 2.9 billion games.
