In general, I agree with your view and I tend to ignore all the opinions, but just sometimes it is worth digging some more. For example, the focusing does appear to be something that may be significantly better with mirrorless, under some circumstances. I sometimes use a Canon 50mm f1.2L. It is a great lens but I have never been able to use it at f1.2 effectively. I will try it with the Sony to see if sensor focusing will add that extra bit of accuracy. Also the eye focusing sounds interesting.
Moving to the subject of lenses, what about colour? Reviews often say things like "excellent colour", or nothing at all, but it is important. Often good colour and good resolution go hand in hand, but not always. When a reviewer says he likes the colour it may be worth investigating.
