Sony just expanded the Walkman line with the NW-S730FK Series that consists of the 8GB NW-S738FK and the 4GB NW-S736FK. Both devices come with a somewhat small 2″ TFT display and support WMA, MP3, ATRAC, linear PCM, ATRAC Advanced Lossless, HE-AAC and AAC audio formats, while images are just JPEG.
If it’s video you like, it will handle movies and clips in AVC(H.264/AVC), Windows Media Video 9 and MPEG-4 formats. Your choice of black, gold, red or pink. No word yet on a release outside of Japan.
