"Today Sony announced a new Metal Gear Solid edition of its W-Series Walkman, to help promote Metal Gear Solid Peace Walker. The promotion makes sense, because both products have 'walk' in the title.
If you're not sold on the MGS Walkman, there's more: The camouflaged headset comes pre-loaded with the Peace Walker soundtrack, and also contains a coupon for unlocking special characters in the game. The Walkman also sports a quick charge feature, with three minutes of charging time providing 90 minutes of playback. Witchcraft!"
