Reports from people in attendance, and subsequently a rough sketch released by Hisashi Yuki all demonstrated that Super Ginrai, TakaraTomy's use of the Powermaster Optimus Prime mold, would be fairly distinct from the Hasbro equivalent. Now thanks to an image snapped during the presentation and shared by Fai Wong, we have a direct look at the images of the prototype and can see a good portion of what's been changed, and how. Keep reading to take a look, along with comparison images and more details!
Our speculation that some portion of the retooling would go towards a more traditional Optimus Prime styling seems to have been right on. The partial view of the vehicle mode has a much less imaginative appearance for the cab. The robot mode changes seem to include the chest panel being restyled, including having a bigger space to show the truck windows through. The forearms are remolded, and the panels on the backs of the arms now fold away rather than sticking out below the hands.
We think the hands now may be normal, 5mm-friendly hands, as the remade guns are shown in the vehicle photo pegged to the roof of the trailer. It's not definitive, but when compared with the look of PMOP's guns in the same placement, it is quite suggestive. The feet are also newly retooled, and quite a bit narrower looking than the originals.
What is not clearly evident is a Powermaster style Titan Master like some were hoping to see here. While that may not be impossible, it does seem very unlikely to happen. This image also makes it hard to see if the head has been changed at all, but going by Yuki's sketch, it probably hasn't.
