Agree that ProRes internal would be ideal just as BMD have used as a secondary codec to raw.
Internal Compressed Raw Codec (such as Braw) even if it has to be a paid upgrade would be worth it as it prevents having to mount a top heavy monitor on a slim camera.
attachable/detachable EVF is also something ive been waiting for in a Mirrorless camera. It would be great to be able to customize EVF placement when rigging up or using a slim (Unrigged) hand held mode.
