Bill, Roger, kuzano and maybe some others are arguing from a false premise. Yes, we are a niche market, but a niche market need not be "a market force" (a term someone else used, not one I am introducing) to be addressed. Epson/Cosina addressed the niche, and the fact that Epson has not committed to the dRF long-term is immaterial.
Zeiss has stated their interest, perhaps even intention, to make a dRF when certain technological objectives can be met.
Would this grow the niche into a market force? I think not. Actually I am dead certain it would not.
Bill, you may be "reality based", but how is that different from anyone else's self-assessment? Implicit in your statement is that you consider anyone who differs with you to be living in some sort of fantasy world, disconnected from reality. That does not mean that I don't value you as a person and forum member. We all live in our own reality. Perhaps a bit different approach and choice of words can keep our worlds from colliding; especially when the OP was an innocent reference to one part of an article where an executive from the (reputed) #5 camera producer feigns shock.
