Mattel toys is taking orders from their retailers for yet another series of dolls. The "Monster High Classroom Doll Assortment" is scheduled to be available in early 2011. They will retail for about $20 (so they must be something more than basic fashion dolls. Perhaps they have additional outfits or accessories). Unfortunately, we have not word as yet on names or how they look. However I will be visiting with Mattel in January, and may have more information after that.
On a related note: The Gloom Beach series of Monster High dolls is still available to order from Mattel. Its looking more and more like these will not ship until 2011.
The Dawn of the Dance series of Monster High dolls is not longer being offered to retailers by Mattel. This might indicate that this series is being set aside for a retailer exclusive. That is, to be available only through one channel.
