After the announcement of Sony a7R IV and RX100 VII, there are still two new unannounced camera codes registered (WW594724 and WW642826), this means we will see two more camera announcements within 1-2 months. These two cameras are not high-end models, could be RX10 V and a7000.
We are now also confirmed that the Sony RX1R II replacement will be announced soon (in the second half of 2019). The upcoming RX1R III or RX2 could feature with Sony a7R IV‘s 60MP full frame CMOS sensor. Stay tuned !
