I really doubt BBTS would put it up if it wasn't an official solicitation, but it is a bit odd that the others like TF Source and Robot Kingdom haven't updated yet. Perhaps they're not sure of their shipping costs as yet? BBTS probably just knows the high demand and wanted to jump the gun a bit to nab early birds. I wouldn't be surprised if the yen price ends up being considerably less than 1:1 with what BBTS is offering - more like 20,000Y or something. That's baseless speculation though, i have no idea what Car Robots Max retailed for?
Edit: Mucho wrong - first japanese retailer listing it for 25,032Y (retail 31,290Y).... BBTS' slow shipping price isn't too much rapage after all.
If you add to cart then hit calculate shipping for Australia, it'll tell you that shipping costs an extra $119.99 for USPS express or $103.99 for UPS Air.
