Unlike the initial one built in Odaiba last year, looks like the construction started with the arms first, instead of from the legs. Then again, they will still need to complete the foundation (feet) and the legs' frame first before the arms can be installed. ^^
Also, looks like there are going to be new markings on the entire statue, for example the body armor:
You can see those white stripes on top of the chest. The marking design is going to be the same as that on Real Grade 1/144 Gundam RX-78-2, I'm quite sure of that. The markings together with the different colors molded for that kit, I believe you can get yourself a highly accurate 1/144 replica of the statue at Shizuoka through RG 1/144 Gundam RX-78-2 as compared to HG 1/144 Gundam RX-78-2 Ver. G30th released last year in conjunction with the statue in Odaiba.
A look (again) at the decal design of RG 1/144 Gundam RX-78-2 from Shizuoka Hobby Show 2010:
Speaking of which, more images of the actual replica of the statue in Shizuoka from Shizuoka Hobby Show:
From the last image, Bandai had outlined the project schedule for this statue:
* Early May: upper body and waist's FRP (fiber reinforced plastic) armors done
* Late May: arms' FRP done, display pedestal completed, lower body's iron frame assembled.
* Early June: other FRP done,
* Mid June: waist, upper body and head assembled, beam saber installed.
* Early July: final tuning of the stance, performance rehearsal
* Mid July: completed
* July 24th: open to the public.
About 2 months away before we get to see him again. ^^
