I received some additional information on the upcoming Fuji X-H1 camera:
The Fuji X-H1 is currently being tested
It resembles the Fuji GFX camera: it has a control layout almost identical to it, but the size is smaller like that of the Fuji X-T2 (see above mockup)
It is targeted towards the video crowd with in-camera stabilization and the ability to record at 120fps 1080 (4k fps will be lower)
The low light capabilities are supposed to be on par with the Sony a7s (ISO 409,600?)
