Sony seems to excel at technological expertise and I think that this was simply a demonstration as to what they can do. I've limited funds and honestly, my NEX-7, X100 and old 1DMKIII fill my digital requirements nicely, so there is no longer a real need for another camera. That said, I'll wait for a FF interchangeable mirrorless and it must have a viewfinder and if EVF, it better be a notch above the NEX-7 EVF. So, limited funds and no real need.
I considered the DP-2. It looks like a great camera for slow, methodical daylight shooting. Once again, I realized that more money spent gives me less to spend on FF. I've come to the point where I need to sell equipment to buy equipment. This makes for a more careful consideration of what I buy. I can buy the new Leica 'M'. but the price paid is selling more camera equipment.
