FansProject will be reissuing their Powered Commander trailer/armor set, compatible with Classics/Henkei Optimus Prime/Convoy figures, for the Japanese market. This time around, it will feature chrome parts, to fit in with the Henkei figure.
Unlike the previous release at TFCON, this will not be limited. It will be available soon.
Thanks to 2005 boards member Red Leader of sponsor Kapow Toys for the heads up.
