I have to admit, this really looks killer, and i am almost tempted to buy... almost. Fact is, as i already have the yf-21 in blue color, displayed in plane mode, and i will definetly NOT be selling this nice toy, i am hopping to wait for a different color scheme one day, and i seriously hope they will make other colors, such as Orange, or Low Vis, or Blackesh maybe (but maybe Orange would appeal to me the most as i dont have any other orange valks, and i had seen some mod in that color which really looked nice). But fudge, i understand why everyone wants to jump on this. This could be Yamatos finnest toy yet for some very long time. Wawawiwa.
Kensei: It could be, however, i had believed the yf-21 to be independent, and could fold without attachments (and i cant remember seing anything attached when folded or unfold, but you could clearly see it on yf-19. Anyways, i could be wrong.
