An update from tfw2005 - looks like there are going to be 2 versions being released by TakaraTomy, which are both different to the Hasbro version... giving the completists, 3 versions to collect. (not me though )

There will be three versions globally of this figure.
The Japan release will be painted in (matte) yellow to match the movie character.
The Hong Kong release will be painted in a metallic yellow.
The North America release will be unpainted, but the outer parts are molded in yellow.
