Sony's upcoming S-Series Walkman has leaked, prematurely listed at French retailer materiel.net. Two versions of the PMP are detailed, the 8GB Sony NWZ-S544 and the 16GB NWZ-S545, each with a 16:9 aspect QVGA 2.4-inch LCD display and integrated stereo speakers.
There's also an FM radio with 30 presets, MP3, WMA and AAC support, a built-in microphone and H264/AVC, MP4 and WMV video playback at up to 30fps. Unlike the OLED X-Series Walkman there's no WiFi, internet access or YouTube playback, but then the S-Series are meant to be a far more affordable breed of PMP.
Battery life is listed as up to 42hrs music playback or 6.5hrs video playback, and there's a nifty little stand for hands-free use. The listings have since been pulled, but the S-Series started from €129 ($183) for the 8GB model.
