Didn't Nikon have to publish a guide to get best performance when the D800 came out? There will be a need for faster shutters as the density increases.
Now, that may be irrelevant here. 35mm needing faster than 1/160s does sound like another mechanism other than user movement. Is there an obvious repeatable direction to the blur matching the shutter? If we use flash sync speed as a guide to the shutter travel time, the 1/100-1/160 ball park would be worst affected by direct shutter movement. Faster than that, you substantially complete the exposure before the curtains close. And if you go much longer, the blur would be averaged out, assuming any residual vibration is damped quickly.
