Not too many weeks ago FujiRumors announced that in 2025 there would be a fixed-lens GFX. Nothing more in the way of sensor, lens...which will come as Patrick has reliable sources close to Fujifilm.
I will get one, whatever lens it has. I currently have the GFX 50SII and it is great (except for focus speed as it uses only contrast detection and because the optics are larger, and thus heavier, it takes longer for the lens to lock in). I was considering the X100VI as a travel camera but I think the fixed-lens GFX will be more flexible in post, assuming it has a 100mp sensor, but even if it was the older 50mp with a faster processor I'd still get it. They could offer a 35mm lens which equates in full-frame equivalent to 28mm, and then by in-camera crop or post crop, you've got equivalencies for 35, 50 and 75 without losing too much resolution. This is what the Leica Q3 does. There is talk about it maybe being a medium format version of the X-pan but I don't see any reason to limit it to one aspect ratio. If, however, it was a 65:24 (x-pan) at the full height of the current sensors 32,9mm, but double the width...??
