Cost of parts is just one component of cost-price of manufactured goods, and often not even the most significant. BW points it out clearly in the article: "The estimate doesn't include costs for items such as labor, shipping, advertising, software development, or patent licensing."
I understand that part, I'm a graphic designer too and I'm aware of all the other "hidden" costs too... but what we don't understand is why a $20,000 camera can't have a decent LCD or at least a decent way to preview an image without a PC... I'm not saying a $28 retina display or the whole $299 iphone stuck on it or a "expensive" $500 LCD... they should have by now at least the 2 year old nikon D300 922,000 pixel LCD.
Hasselblad had their chance to change this with the H4D-40... pentax 645D has done it, I know pentax has all the pentax k series to help with LCD units demand... but how companies like Ricoh have close deals for LCDs and hasselblad and phase one have not?... It's that low the MFD demand? or how come sony, nikon, canon, pentax, kodax, panasonic, samsung, Fujifilm, olympus, ricoh, leica, coby, LG, HTC, Motorola etc etc have done it? maybe next photokina...
P.S. I understand all the heat and processing power issues too, but pentax and leica have already done it, so that shouldn't be an issue by now.
