Originally posted by Winder I think the new 100MP BSI sensor is going to be very expensive. It will be a $10,000 body if not more. The Phase One is a $45,000 body, so if Fuji hits the $15,000 price point they will sell all they can make. If Fuji wants to run even 3fps with 16-bit RAW (100MP) then they need a huge amount of processing power and memory. Even with a lossless compressed RAW they will be near 100MB each. If Fuji uses X-Trans they will need 2-3x more processing power and memory since Xtrans is pretty hard on system resources.
If they can't hit at least 3fps, then people buying Canon/Nikon aren't going to be interested anyway. Its got to have the speed that these users expect. Both AF and fps.
Fuji doesn't use Xtrans for their medium format cameras. They just use standard arrays.
But I agree with your general premise. This camera is going to be expensive and will not be an adequate substitute for those used to standard SLR/MILC function. I don't even know if it is going to have PDAF points on the sensor, because otherwise contrast auto focus with these cameras is not great.
