Looks like Bandai has confirmed the 1/100 MG Tallgeese for a January 2013 release (80 or 90 days). With the price it is going at (I think 3800 yen?) and a “want” rating of 10/10, looks like this kit is jumping to the front of the line for my MG “must haves”. I have always wanted to build this kit, and I have held off on the HG in addition to the HG of the Altron Gundam.
Although similar, the joints are probably improved, as well as a redesign of the weapons, the shield, and the boosters look a little different.
