Lenovo has confirmed that its next flagship phone, the Z6 Pro, will be launched in China on April 23. Much remains to be known about the device but it will feature a Snapdragon 855 and, perhaps, a massive 100 MP camera.

Well...going by the density of 1/2" 48MP...about 2/3" (should still be slightly bigger but no such format) 100MP, 2/3" was Nokia 1020's sensor size, but I don't recall Sony announcing a 2/3" 100MP, maybe Lenovo negotiated a debut?
