Future HGUC release include Messala - the transformable MS/MA from Gundam Zeta.
I'll take the news with a pinch of salt though.
See the price? It says 2,400 Yen without tax and 2,448 Yen inclusive of tax. But it should be 2,520 Yen instead. Bandai would never make that kind of mistake, when it comes to pricing. ^^;
