Newswitch published a new interview with Yasuyuki Nagata (Senior General Manager Sony Imaging Products & Solutions) - here is the recap from SonyAddict:
The introduction of more high-end cameras is exciting and will help increase lens purchases
There are more high value-added and high-priced options than ever and the trend should continue for three years
Sony has around 60 lenses already, but still have dozens in mind to expand the number of people interested in their cameras
There was more interest than expected in the 200-600mm
I am concerned about the rise in material costs, but I will not compromise for miniaturization and weight reduction of the product
The one mount strategy has worked for Sony and it lets photographers interchange their lenses more freely
The cost of camera/lens development is on the rise and Sony is doing their best to deal with it
Smartphones are a big part of the market and if 1% of smartphone photographers got interested in mirrorless it would double the market
Smartphones currently fail at telephoto and wide-angle photography
Compact cameras like the RX0 are still growing, but other areas are remaining consistent
