TF5 JP Dual Model Kit DMK04 Optimus Prime

TakaraTomy are releasing another large size Movie model kit under the "Dual Model Kit" banner, with this one being DMK04 Optimus Prime.
But this one is just the DMK03 model kit from TF4, with some minor colour changes and a display stand.
No release date or price yet, but should show up on JP sites soon like HLJ and Amazon.

DMK01 was the first version Optimus, which was available in solid colour, transparent, and a competition figure done in red and white that is said to only have 4 produced.
DMK02 was Bumblebee.

The first three and the translucent version Optimus is on the right of this photo (I never ended up putting decals on DMK03, as the previous ones were painted, and I didn't trust myself with the flame decals... yet).

I could never figure out why they are called "dual", because there is nothing significant like being able to build either mode... but I think it is because any of the optional parts are done in pairs (like faces, hands and weapons).
