I agree with you re the A6xxxx cameras but more to the point I'm not too interested in E mount any way, I sold my A6000, I don't know why I bought it, must have been one of those spur of the moment things, buy in haste, regret at leasure . Also agree re the Fuji but their lens price structuring is a bit steep, especially when you can see whats on offer from Canikon and Olympus.
In the Sony collection I much prefer A mount although I don't want to venture into FF, currently, I'm running a A37 with a few lenses and an Olympus EM-10 with just the kit zoom. Both are nice to use, but I prefer the Olympus colours and I have no problem with noise as the biggest I go is a large HD monitor screen. I have no intention in enlarging any further so noise is academic.
The new Canon EOS M -5 looks good, its a more sensible size for a CSC than the Olympus EM-10 and the lenses get good reviews and won't break the bank. It has some performance issues which may put off potential buyers especially at the huge launch price they want, but as a stills camera for landscape and general photography it scores well. Wait until prices fall.
I always liked Canon lenses right back to FD manual focus on my AE-1 Program. If I was to return to APS-C DSLR it would be a a coin flip between a used Canon 60D or a used Nikon D7100. I could equip both cameras from the vast used lens market. But, they are big and heavy.
We are in uncertain times for the camera industry, and it will be interesting to see what the future holds for them, I can see a couple of casualties coming and possibly some amalgamations down the road, but it won't be Canikon on either count. I suspect Fuji will survive as I think M/4/3 will, both have carved out a niche market with loyal users. Panasonic are not doing well but like Sony will probably absorb losses in other areas of their electronics empire.
I think we all to a point have the 'grass is greener on the other side' syndrome, when you buy into a system then wonder if XYZ would have been better, and quite often people do jump over. An expensive leap I might add, I did it a few years ago and I'm still pondering my next move.
