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?

Since the newest announced E-mount camera is the A6000, and is not a top line E-mount camera, I'm guessing that Sony holds back a few things.

The A7 is also E-mount, is higher placed than the A6000, and has 1/250th max synch speed.

Most mirrorless cameras, including all E-mounts, have shutters, and those shutters still need to be fully open for X-sync. It's not the mirror that's responsible for limits on max X-sync, it's how quickly the shutter can open (if it's not a EFCS) and close.
