The 2018 Photokina show is now over and here is an updated list of registered but not yet officially announced cameras:
Nikon N1721
Digital camera
made in China
Wi-Fi (2.4 GHz) · Bluetooth installed
AC adapter: EH - 73P
COOLPIX A1000
Sony DSC-WX 700
Wi-Fi · Bluetooth installed
Sony DSC-WX 800
Wi-Fi · Bluetooth installed
Battery: NP-BX1
Leica 3952
Digital camera
Wi-Fi · Bluetooth 4.2 installed
AC adapter: ACA-DC16
USB × 1 (charge compatible) · HDMI × 1
Leica's 3952 is the new D-LUX, because the AC adapter is the same as the C-LUX and the radio has the same performance as the Panasonic's DC-LX100 M2.
Ricoh R02010
Digital camera
Wi-Fi · Bluetooth installed
BJ-11 battery charger
Ricoh's R02010 is expected to expect the Pentax brand new SLR because Bluetooth is not described in the GR III developed and announced last month (although Bluetooth may be added in the product version).
