X-Plus updated there site with both King Ghidorah and Godzilla '64, first Ghidorah. We knew this figure would be big but per the site the figure stands 37.5cm tall and 78cm wide and it not only the size that is big but the price too at approx $360 US it includes a burning flying saucer (15cm in size). It should be available December. Update: The correct size of the figure per the Ric-boy site is 32cm to the head, 47cm to the wing tip height, and 62cm wing to wing width. Also the Ric-boy version will have two flying saucers one regular, one burning, and the size is smaller 9.5cm.
Godzilla '64 is a Real Master Series figure (resin) he will be 31cm and will run approx $285 US.
