The Art Asylum Blog has been updated with a little bit of information about the new Ghostbusters Minimates and Ghostbusters Fans has managed to come up with a few new details. There will be two releases that will have several Characters in each. The first group will have: Egon, Peter, Dana (as Gatekeeper), Louis (as Keymaster), and a Terror Dog. The 2nd and more distant release will have Ray, Winston, Gozer, Stay Puft and Slimer. Each figure is about 2" tall and they should be fairly affordable.
UPDATE: Also coming from Diamond Select Toys (the distributors of Minimates) will be replica Ecto-1 license plates and a Stay Puft Marshmallow Man bank. View a gallery from the United States Toy Fair via Action-Figure here.
Special thanks to Gareee for the heads up.
