Just to chime in with my 2 cents... short answer, yes... long answer, maybe... well depends... My personal opinion is I dont personally upgrade until my business needs demands it and or when I've outgrown my current gear... So new gear, for me, offers a new ceiling of quality to master, a new challenge, a new expansion upon my current limitations that I can learn to achieve... For instance I shot a wedding ceremony with my 5d3 and got away with ISO's nearing at times 20,000... no flash for ceremony. I didn't think twice about it because I knew once processed, they would look stunning at 8x10's and with a little bit more care, would make great wall portraits... You just couldn't do that with the 7d, 5d2 5d classic, hell even the 1ds3. And the images, focus, quality looked great... That, to me opens up a world of opportunity to expand my skills and services... Is that worth the $2000 premium over the 7d and 5d2 right now? In my current example, yes.
