Sony a7R II
Sony a7R II from the specification looks to be a revolutionary camera. Its a full frame, mirrorless (hence smaller form factor and less weight), five-axis in-camera stabilization, 42 mp resolution (great for landscape and cropping), 399 focus points. Need to see how realistic the EVF is.
Nasim Mansurov has a nice write-up on this recently announced camera.
Initial Reluctance to High Resolution
Neil van Neikerk very well summarizes what I also initially felt about high resolution. He highlights the enormous leeway that D810 gives with output still being crisp and large with detail. I learned the same thing with my D800E.
