Zero was originally due out in Japan this month, but has been delayed until October. The model kit includes a number of accessories, such as Z-saber, Z-Knuckle, Buster Gun, and interchangeable faces. All this comes in an incredibly awesome boxart, pictured in the above. Not sure if its Nakayama's doing but, man, it's a beaut.
