Apprently Archos is about to add another player to its Gmini line after the introduction of the Gmini 400. The New music player is called Gmini XS200.

The Archos Gmini XS200 plays MP3, WMA, and WAV music files. Note that this is a pur music player in contrast to the Gmini 400.

The Battery life is 10 hours.

The Gmini XS200 will come available early October. Suggested retail price for the United States will be $249.
