About the new 100MP sensor made for Fuji and Hasselblad Sony writes:
There is no info about their Full Frame roadmap but the PDF file contains a lot of info on their industrials sensors. Some of that tech will find its way on FF sensors too I guess: http://www.sony-semicon.co.jp/products_en/news/detail/170301.pdf
My wel known stalking point to Sony:
I would recommend you using the large 55x41mm to launch a new medium format system camera.
