Does anyone know what the reason may be that even the newest announced e-mount camera's flash sync speed is only 1/160 s?
Is it not possible to improve upon that with a mirror less camera for some reason or do just too few customers care for it to be faster?

The A7(r) cameras are very light. Due to the sensor size, the shutter is quite large and has a lot of mass relative to say a micro four-thirds shutter. Moving the shutter fast enough to get 1/250s sync speed would multiply the shutter vibration issues that people are already complaining about.
