Another iPod-killer from SONY

One of our contact hgas told us that SONY should release in a near future a MP3-like player to celebrate the 25 years anniversary of the Walkman. We could only get few information regarding this new product: it will be a 20GB HD-based player, and will have a baterry-halflife much more superior than the one from the iPod. It will only play Atrac3 format audio file.
Sony is preparing its weapons to fight against Apple and its iPod.
