Lets get real here!
$6.000 is alot of money to spend on a camera that will be outdone by something that appears two years later. $9000 for something like that is not possible to market to sell widely. Notice Canon and Nikon have different versions of the same camera at various prices. That is so they can make money on one platform. Leica cannot afford to sell this above $6,000. $7,000 would really hurt, but alot of people could swing it with some sacrifice. $9,000 and up would limit the camera to a few sales, and what would one do when at that price level, we are talking about medium format digital (Pentax is reviving their plans for a 645 Digital, and their lenses are cheap and very good, I have them, I know, some better than the Zeis they put on Hassys and Rolleis).
Basics to business and profit are good marketing and large volume of production with reduction of product price. No company is immune to these basic market facts, not even Leica. There comes a point where the business model fails, and if you price yourself out of a larger market, and you loose money, all you have to do is look in the mirror to see who is at fault. this is economics 101. Even Mercedes Benz knows better. They kept US prices lower even though the Euro was killing the dollar. Why? Because they knew there was a price level that they could sustain here that made sense. If it went up too much, you would turn away customers, even if they do have money. People who have money don't like to get ripped off either!
