7D mark II released just two years ago. I think there won't be 7D m3 before end of 2018.
It will be 2017 because of the D500. They won't be able to make up the gap with firmware features on the 7D2. They have also invested heavily in the segment, as is demonstrated by the number of features given to the 7D2. That means they'll defend it just as heavily. So I do expect a 7D3 in 2017.
I also expect that 7D3 for more reasons than just the D500 - the 7D2 was the APS-C version of the 5Ds/r sensor pixel density-wise. I fully expect the 7D3 to have the APS-C version of the 5Ds/r2 sensor. Which if the 5Ds/r goes to 100MP-120MP will mean a sensor between 38MP and 48mp. I also expect not only the ADC but BSI, as Canon has been working on both engineering projects since 2010.
If the 5D4 has a 24MP sensor, then I'd push my estimates out to 2018-2019 for the 7D3 and 5Ds/r2 respectively. But that's a long time to allow for market erosion in a volatile economy. If the 5D4 has a 28-32MP sensor, then my estimates are likely correct. If the 5D4 has a 28-38MP sensor with BSI, then you could probably take my prediction to the bank.
But I'm not a betting man, so daydreams these are until reality sets in.
After all, what is life if we can't speculate about our pet ideas?
