nex-7 or nex-6 which is ultimately better?

I had the NEX7 and replaced it by the NEX6 some months ago. The NEX6 is better in every aspect that has been changed IMO, controls, high ISO, no color cast with manual wide angles, rubber grip (then went off on my NEX7) WiFi etc., except of course for the nice 24MPix sensor. Would I do the change NOW? No, I would wait for the NEX7 successor.
