FujiRumors.com reports it has information that a (likely video-centric) version of the X-H2 camera will come out in 2022. This would explain the confusing signals the rumor site previously received indicating that their might be two versions with two different sensors.
The new X-H2S is rumored to have a 26 megapixel sensor, allowing for 4K video shooting. Another camera, with name as yet unknown, will have a 40 megapixel sensor.
