I think my subsequent reply brought out 2 reasons why it will not be acceptable on a Pro-level FF camera like the A850 & A900, or at lease at the moment with its present sensor density and processing speed.
Users will be complaining about shutter lag and blackout time (remember FT/ MFT does not have a mirror) if they compare with others.
1) larger sensor size as in dimension will increase it damping and tracking time.
2) Higher density will increase processing time.
Just take it with a pinch of salt, I might be totally wrong.
