Demonstration of rumoured new device backs up recent speculation.
A video showing what is allegedly a new gaming smartphone from Sony Ericsson continues to fuel speculation that a handset is in development at the company.
Technically the demoed handheld resembles a PSPGo with a touchscreen and trackpad at its centre.
Bert Nordberg, Sony Ericsson CEO, recently addressed rumours of such a device, though the company has made no official statement.
