The Atmos Duck Camo Convoy comes out March 26th, along side the assortment of Duck Camo shoes and clothing (and by the looks of it, a special themed wrap for a particular model of Mercedes-Benz).
The toy is listed for 19,000yen (plus tax).
The Atmos news page is here of all the different Atmos products for this release, and images of the Transformers items are mirrored here for when the original site disappears.
