Un noticed improvement for the D7200 ?

I note the D600 has a lock button for the control dial...along with a 24 mp sensor this would be a great improvement for a D7200

I think it would be, I'm really curious what sensor will go into the next high end Dx. I think 24mp in Dx will really limit landscape folks due to sensor diffraction.

same sensor in my D3200 ....no problem ..take the pictures .and have happy customers..
