I would only disagree that the 6D IQ will surprise people...unless those people actually expect it to be much better than any other Canon sensor. Canon has not yet demonstrated an improved manufacturing process, so it is doubtful that the 6D sensor will be radically changed in any way.
true dat. and extending this logic, one has to conclude that whatever sensor the 7D2 gets, it may be incrementally better than the 7D1 but still won't compare with 6D or 5D3. I mean -- even if they could, its not likely that Canon would produce a crop body that would exceed the IQ of a more expensive FF body in the current line-up. It wouldn't surprise me to see (in the 7D2) an increase in MP count, improvements to AF and perhaps even fps, and a measureable improvement to the ISO and noise performannce, but I guess I'm not expecting to be astonished by a market-disruptive IQ or DR. is anyone else?
someone in another thread (pardon the lack of reference) has already suggested that Canon has telgraphed their FF sensor offereings for the next 2-4 years or so, with the 1DX, 5D3, and 6D releases. The big mp body is the unknown at this time, and I suspect this one to be optimized for DR and low ISO, expecially its first release I doubt it will match the ISO performance of the 5D3 for example.
but they have not telegrahped their crop sensors for 2013, and the silence of the 7D2 in this regard is defening. I can only hope that the delays mean a new sensor and not a re-worked t4i sensor.
