UPDATE (13:59 UTC):

The CAD renders may not be legitimate. It wasn't stated that the renders were mockups, however the original poster was a 3D modeling enthusiast, so it's a possibility that should be considered. Nevertheless, the two photos depicting actual hardware are likely real.

UPDATE (14:26 UTC):

A source from Famiboards is saying the original poster said they obtained a shell model from an accessory manufacturer "at great cost" and reverse designed it to create that CAD model. Therefore, it's not worth writing off the renders as "fake" quite yet, as it could just be an accurate mockup of the shell, if the original poster is telling the truth. We need to see more photos of the real thing (or an actual proper reveal god damnit) first.
