Twice (?) the size of a regular Revoltech in terms of box size.
Geno Breaker - Sample display.
Still 2 months away from its actual release date, but it seems like everything is ready to be released tomorrow. ^^ Also, we're not shown its depth, but seeing how Blade Liger is positioned in the box, I bet it's going to be quite a thick box.
July 15th release, 4,900 Yen (inclusive of tax).
More images and release info of this Revoltech figure can be seen in this and this previous posting.
