I think the concern is not so much the 7DII, but that Canon does not seem to have any new sensor technology on the horizon. Canon 1DX and 5DII, III owners are concerned that the high resolution sensor market has been conceded to Sony. The concern goes beyond the camera body. I have not bought a new lens in a year and I will not buy another lens for my 5DIII until I know that my investment in lenses will be worthwhile one in the long run. I would have already bought one or two new lenses but I will just live with what I have until I am sure Canon wants to keep my business. I hate to say it but I don't really care about their larger market share and servicing another market. I care about me.
