Measuring in at 7.2mm thick and weighing 62 grams, you can expect a 2.8-inch OLED screen, 16GB storage and up to 29 hours of audio playback or 9 hours of video.
However, if the 2.8-inch screen isn't big enough for your movie marathon sesh, hook it up to your TV with the optional A/V out cable for your films on a bigger screen, albeit in standard def.
The skinny PMP will support a wide range of file types including WMA, WMV and MP3s, which can all be imported quickly by either dragging and dropping from your PC, or via iTunes using the included software.
The Walkman A845, complete with supplied noise-cancelling headphones, is set to hit shelves from February 2010. Pricing is yet to be announced.
We'll be getting hands on with the A845 at CES so be sure to keep it locked for all the latest news and videos on Stuff.tv – plus remember to follow us on Twitter!
