Sony officially registered a new camera with the code “WW213188”. It usually takes 1 up to 3 months until this camera will be officially announced. The registered model has Wi-FI but no Bluetooth. This camera could be the A7sIII the A6700 or a new compact camera. My guess is that this is for the A6700. The A7sIII is probably going to be announced in October-November and feature the new Sony OLED EVF that goes into mass production in November.
Also keep in mind there will be another press event this summer to definitely launch the new 400mm f/2.8 FE lens.
