Premium Bandai is re-releasing their Robot Soldier from their "Souzo Galleria" line but with LED-light up functionality. Although great news for people who have missed out on the original from 2013, unfortunately this new version will be Web exclusive only. There are other ways to get it but you still have to be in Japan. The new LED light up version will also be available (very limited) at the Ghibli Museum located in Mitaka Japan.
Price is listed as 3,888JPY and will be available November 2015. For anyone living in Japan you can preorder through Premium Bandai website here: http://p-bandai.jp/candytoy/item-1000098210/
