That Sony S-Series Walkman we spotted a couple of weeks ago has reared its speaker grill-laden head once more, only this time in what looks like an accidental unveiling on French retailer Materiel's website. According to the specs list -- accompanied by some new official press shots that give us little reason to doubt its validity -- the 8GB NWZ-S544 and 16GB NWZ-S545 feature a 2.4-inch QVGA widescreen display, stereo speakers, a microphone, FM tuner, a Li-ion battery for a reported 42 hours of audio / 6.5 hours of video, and what appears to be a built-in stand for convenient video watching. Codec support includes MP3, non-DRM AAC, WMA, H.254, MPEG4, and WMV. No fanciful colors like in the first pic, we've only got black listed for now, to the tune of 129€ ($182) for the 8GB model and 149€ ($211) for 16GB. We're still waiting on Sony to fess up to the device, but really, it can't get much more official. A price and release date for US would be nice, though.
