This resin kit uses the licensed movable frame from the same company, which provides a wide range of articulation for a normally for-display-only resin kit. Not a new product anymore, as the same inner frame is also used for several other models made by G System Shop.
Articulation aside, I'm sure many are highly anticipating the beautiful exteriors of Sinanju, especially the yellow ornaments on the chest area. The quality of the company's previous work like 1/72 Sazabi Evolved Ver., PG Jadg Doga conversion kit, or 1/100 Qubeley Genuine Ver. showed their confidence in sculpturing those difficult parts. We'll just have to wait to see the finished work ^^
This 1/72 Sinanju is currently under development, and is scheduled to be completed in October. Fans who are interested have till end of this month to pre-order it from G System Shop, and the first shipment will start in mid December. The pre-order price is $370.
Also, updates on 1/60 scale UC0080 rivals of Gundam NT-1 and Kampfer reported some time ago:
Previously, it was reported that Kampfer uses the inner frame of PG Zaku II. As a matter of fact, you can see from some of the photos above that it's indeed using the parts from that PG kit for its leg. However, on the homepage, the movable frame made by G System Shop is shown as the inner frame for both Kampfer and Gundam NT-1 instead. o_0
Guess we'll need more updates to confirm on that ^^;
