Sony has registered three new camera models in Asia:
1) A new low-mid level camera with 2.4GHz WiFi (code WW594724)
2) A new low-mid level camera with 2.4GHz WiFi (code WW642826)
3) New High End camera with 5.8GHz Wifi first introduced with the A7rIV (code WW942051).
Expect those camera to be announced within 1-2 months. SonyAlphaRumors reports there will be an announcement in August already!
It’s unclear what these cameras might be. The entry level cameras could be new RX models. The High end camera could be the A9II or A7sIII or the A6700 if Sony hasn’t forgotten they have an APS-C line :)
