Yesterday a single press photo of a new Sony Walkman MP3 player leaked. Today Sony has gone official with the leaked A860 from yesterday and a bunch more new digital audio players. The first player, which was the one in the leaked photo yesterday, is the NWZ-A600 coming in 8GB to 64GB capacities. It has a 2.8-inch display and will play common music formats. It also supports MPEG4, AVC, and WMV9 formats for video. The battery is good for 23 hours of audio or five hours of video.
