Here is something else I would like to add. I already know that the guys who make the Ghostbusters Minimates can't make the Ecto-1 because Mattel Toys have all the rights to it for their own Ghostbusters toys, but there does not seem to be anything keeping them from making Minimates Vehicles of Ecto-2, Ecto-3, Ecto-Bomber, Ecto-Ichi, and the Ecto-Junior.

I would also like to see them make Minimates figures of The Junior Ghostbusters.

I don't think we'll be seeing any GB related vehicles, the vehicle lines in general aren't selling well

What about the vehicles that were made for the Halo & Back to the Future lines, they seem to be selling very well. Every time the Toys R' Us in my town gets them, they always sell out of them in about 1 day.
