You know guys, perhaps the W.S. VF-1S Roy is not a Limited Edition item. As another member pointed out there is no "Limited Edition" wording on the box or anywhere else. So there maybe hope they may reissue it again. I think the only true limited edition Valks are the Low Viz 1, which there is a "Limited" word on the box, the JBC card Black VF-1J (only 4 or 5 in the world) and also the W.S. VF-1S Hikaru (where Yamato has annouced only 250 units would be produced)
Take for example the Revoltech Ultra Magnus, when was released last year, it was a hobby specialist shop exclusive, but just last month, they reissue the Ultra Magnus. I know more than a few friends who are cursing Kaiyado for that
So is W.S. VF-1S Roy truly limited, who knows, only time can tell.
