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.
