>>If Cosina manufactures a digital RF, they then have to the subscribe to constantly updating the technology in order to keep the camera marketable/competitive.<<
Perhaps so. But I bought my 3MP digital point-and-shoot five years ago (a Canon G1), and it remains more than functional. I think in the meantime that digital technology has matured to the point that something in the 6-8 MP range with stable software would not have to be updated all that frequently. Leave it to Leica to define the top end. I think there's a market for several thousand units of an affordable digital RF chassis to accomodate classic users. We're talking about a group of folks using 50-year-old cameras, so I'm not certain how concerned they would be about constant updates to a stable, functional system. And from a business point of view, $125 profit, after manufacturing and marketing costs, on 2,000 unit-sales is still a quarter-million dollars. Not going to make anyone rich, but it pays the bills for a few weeks.
