However, Hasbro PR did confirm with us that the upcoming MP release will not differ in any way across markets. The toy you can now preorder at EB Games (and Entertainment Earth) is the same as the one offered in Japan by Takara, Japanese voice clips and all.
While speaking of MP-44, we have some more news for you. These are images of the production prototype of this toy, where we can see the different plastic used. We do see some die cast on his crest. These were posted by Takara on Twitter.
