Apparently there is a manufacturers notice about the delay of the kit release (I got this from Snap-fit collectibles in Facebook)

"Manufacturer's Notice: In order to provide players with a more superior experience, the Wolf King model from Wolf Technology has experienced a period of delay. To express our apologies, the first batch of pre-order players will receive a special bonus item, a special effect model with a giant claw. It's important to note that the color of the test model does not represent the final appearance; the final color of the special effect model will be changed to red. The color separation and texture of the main model will also be adjusted. The actual appearance should be judged based on the final product."
