Personally I don't really care as much as long as the traditional ES readout speed is in that goldilocks zone to avoid rolling shutter. I don't know a lot about it between a camera like the R3 that is fast enough and global shutter. Two things I've read is global is better for flash and fast light source changes like flickering. If you primarily shoot outdoors then a fast non global shutter would work just as fine. I think?
We will see. I'd even tale this and be happy with EFCS but I figure sensor tech will outpace it. Cameras without mirrors cost less to manufacture and getting rid of high speed/usage shutters will also bring their costs down.
