With what appears to be an accidental re-release of its announcement of the BarbieGirls online world launch, Mattel shed some more light on the tie-ins that will be available with the accessories to the virtual world. As previously announced, the world is accessed via the USB key inside of $59.99 doll-shaped MP3 player with a 512 MB memory -- now we know it comes with a belt clip, storage case, and adjustable ear buds.

More significantly, though, Mattel will also sell accessory packs, which will unlock new bonuses and content, like accessories, fashions and pets, in the BarbieGirls world, at a retail price of $9.99 each.

Mattel also says it plans to reach four continents and more than a dozen countries this fall on an unspecified date, launching in five additional languages around the world, including Spanish, French, Italian, German and Portuguese.
