X pro2 what do you want to see?

I did a search and didn't see a thread for this.

So what would you like to see in a X pro2?. It is a camera I am going to look at along with the Olympus OMD-EM6 when they come out I would like to see the X pro2 with weather sealing, better ISO, Better AF, and better firmware support. And on future lens better AF build I played with one at the camera store yesterday and the lens clunked with every focus movement.
