The unveiling will follow the introduction of a completely revamped iPod lineup by Apple just two days earlier.
Although Microsoft itself has remained tight-lipped regarding the iPod competitor, little is not already known about Zune, which is being manufactured by Toshiba.
The device will feature a 30GB hard drive, three-inch TFT LCD, an FM tuner, wireless 802.11 b/g, and USB 2.0 support.
Zune will connect up with a new music service specially designed for the player.
Zune will additionally feature social networking capabilities, with a focus on sharing music and music-related content.
Users will be able to link up with "friends" and stream music and playlist data between devices.
