They have delivered the Mini with their V2 4K sensor. I think it has the lowest reviews of pretty much any camera I have seen on B&H. Ever. This won't deter everyone but their poor rep is preceding them.
PS. I actually like the 4.6 image quality quite a bit but, to my eyes, A7RII with an external recorder looks fine as well. And, should Sony decide to really decapitate the market, it can easily release an A7SII and/or an A7RII based camcorder, which would add the 10-bit color depth and a higher bit rate codec for around $5,000. (plus the auto-focus from A6300) And that will be both the knockdown and the knockout punch for BMD.
