Mamiya had historically made some damn awful deal with MAC, (Mamiya America Corp) to distribute Mamiya products in USA at very inflated prices.
These middlemen, oops, 'official importers', managed to mark up everything so much, that people found most products, like Mamiya 7's to be almost half the price in expensive Europe than they were in USA. People imported privately, eBay worked its thing, and litigation followed - note the wording about USA buyers in that listing.
Hopefully they can get out of it this stupid contract, and make their prices competitive worldwide. there's no room for MAC and its greedy markup, in the survival of a great MF manufacturer.
