Some of the specs of the a99II and there functionality. From Sony PDF brochure

12fps

-Enhanced spot metering Bright monitoring The spot exposure metering position
can be linked to the focus area when
the Flexible Spot or Expand Flexible
Spot mode is in use. You also have a
choice of Standard or Large metering
spot size for optimum exposure with
the widest range of subjects.-ISO AUTO Min. shutter speedThis function sets the shutter speed
above which ISO sensitivity will begin
to change when the camera mode is
set to “P” or “A” and “ISO AUTO” is selected.
The ability to specify a low ISO
AUTO limit can help minimize subject
blur when shooting moving subjects
I saw a video on youtupe where you can move autofocus points from PDAF to on sensor PDAF just with the move of the joy stick this is very good both system they will work together when lens and shooting situation allowed. For me is a great camera and have to wait and see the final price
