Two days ago Leica registered a new D-Lux Type 3952A camera in China. The current Leica D-Lux 7 camera is model 3952 (already discontinued at Adorama, Amazon, and B&H Photo) – this indicates that only minor upgrades will be introduced in the new 3952A (like increased internal memory size, new menu/software, etc). The 3952A could also be a new limited edition version. I do not expect any major changes in 3952A like sensor size, design change, etc. simply becuase Panasonic doesn’t have a new LX100 model and if they did, the new camera would have a different nomenclature/model number.
The Leica D-Lux 8 will not have an APS-C sensor and a fixed prime lens (obviously)
The last Leica D-Lux 7 camera was announced in 2018:
