As reported by SSG the maquette is now up for preorder at, and will be exclusive to, Cartoon (preorder Nov), and the GG site (preorder Nov) as well.

Personally I hope this isn't the last of the CW Maquette's. I'd still love to see Grevous, Anakin, Mace, Dooku, Durge, Ki-Adi, Aayla, Shaak Ti, Kit Fisto, and Sideous someday. Also with the new CW series coming next year there should be plenty more character to choose from.
