The interview was more open than most and I respect that, he did miss the glaring neglect of the flash system though and that is a factor for some buyers
But I think it is a mistake to assume any of the "not quite sure" points raised isn't based on a technical level be it AF or flash
The form factor isn't really suited to some users it's a simple as that really but there are others
Mirrorless brings additional problems to the table vignetting and distortion are much bigger issues due to the lens sitting so close to the sensor, even with these addressed with software for many users there are no obvious reasons to switch unless you collect some of the smaller prime lenses
It's not quite the magic bullet some makers would have folks believe.
If you need the flash system, then not having it is indeed a glaring neglect. Otherwise you don't care.
I have had no issue with vignetting and distortions, whether this is due to some software magic or great lens design I do not know, nor do I care.
The reason for me to add the Fuji to my bag was that I simply like the files it produces. The fact that I can see the image in the EVF roughly the way it looks on my computer screen is very nice, too. But then, I am not a fan of the D800 OVF to begin with. And, for me, trying to do manual focus with an OVF an exercise in frustration.
Which is simply another way of saying that mirrorless has some advantages over a tradition SLR, and traditional SLRs have some advantages over mirrorless. What will make people switch in the future is that camera companies will stop producing mirror boxes to cut cost. On-chip AF might be another reason.
I wish there was a camera that was as good as its makers claim
