Walkman S-series device in the chute as demonstrated by this S740 model seen hanging out at the Sony Dealer Convention in Japan. Hard data is scarce but visually we can see a slightly tweaked industrial design with beefier earbuds and a lack of stereo speakers -- at least on the front. Otherwise, we're told that these will ship in 8GB and 16GB capacities.
Update: Looks like a few more images have leaked out -- it must be true, right? Thanks, Glenn!
