New Sony interview explains why A7rIII has same Megapixel number and no body size increase

Hiroyuki Matsushita, Yasuyuki Nagata and Hirokuni Miya

Imaging Resource interviewed three Sony managers

We always listen to customers feedback
Only few customers asked for a resolution increase. That’s why the A7rIII still has the same Megapixel number as the A7rII: “yes, some customers want even higher megapixels. But a majority of customers requested different areas of development such as longer battery life, for instance or faster autofocus, or even the picture quality in low-light conditions. So considering that kind of feedback, we decided which way we should go for the third generation, based upon the customers of our Alpha 7R-series.“
Technology development moves faster than expected so customers sometimes don’t ask for certain things sony can actually do
Unlike the A9 the A7 series is made for a wider range of customers (male, female, young, senior). And for that range body size matters.That’s why the A7rIII kept the same light size/weight.
Sony did decide to NOT adopt XQD cards because accessibility of those cards is still limited

Overall this is an interesting interview I recommend you to read in full!
