There's no indication from the runners that more parts will be added onto them in future "expansion".
The elbow joint uses only two parts! And look at the shoulder joint, it's molded together with the shoulder armors. Not an ABS part, I hope it's strong enough for a lot of action XD
The face and the neck area is molded on the same part - the same design from HGUC Nu Gundam.
The 'connector' on the backpack is even more visible now. I wonder what it's supposed to be used for. ^^;
Too bad there's no photo on the website showing the parts for the legs. I would love to see how the 'swinging' ankle joint works ^^
The rest should be the same as Exia's leg design.
00 stands taller than Exia?
