I dont know if that's the right audience. Most people who buy retro style cameras buy them because of a trend and not to make pro video productions. I think in that case 4k @120 FPS or 6k is kind of a wasted feature since most of these people probably dont even know what card they need for that. And people who need these features want a pro body and if its only for ergonomics.

Eh... Nikon tried this as well. The XT series are great looking cameras but what makes Fuji stand out is their color science and in-body film emulation. Companies that copy this feel more like having a camera with Instagram filters applied. It takes a bit more than a retro design to mimic Fuji's success. The lenses are also made of a went that are contrasty. The added DR options adding more details in those shadows give each photo a film look. Everything works together to make Fuji standout.

Many of us tend to lean towards the XH series which is more professional camera with the same film emulations in a modern body. These are as highend as it gets before their medium format. Nikon and Canon need to take notes and not just replicate the classic body design.

The Canon R50 isn't mentioned here. It's also a APSC camera.
