Before anyone get too excited, search "hachette collection tomcat" on ebay and look at the price..
From what I can tell, their business model for these large model are subscription service, and they mail a set of pieces to you every week or every month. It may take 50+ sets to complete the model. Some initial sets will be sold in magazine rack in e.g. 7-11 in Japan at low price to entice customers.
