Had a look at Justowen's JP Animated Arcee yesterday, and compared it with my US version, and the running change described above matches the JP version. The JP version has a matte/duller pink plastic with less speckle, so I guess Hasbro got some more produced for their TRU stores when TakaraTomy were producing theres. Not enough demand for a new production run of their own, but worth doing while the JP ones were being produced. It just meant a different colour plastic, but kept their black decos (JP has brown).
