Like I told you before it’s extremely unlikely that Sony will announce some E-mount stuff.
The key announcements will happen between Sept 18 and Sept 27 when Sony has two conferences and Zeiss also another one. That’s what we will get with 100% certainty new E-mount lenses. Still unconfirmed is the High End APS-C camera and A7sIII will be announced at photokina or in their next press conference in mid October.
