The Leica M EV1 is the first Leica rangefinder without... the optical rangefinder. In its place, a useful EVF, which can make manual focusing much simpler.
Fujifilm's X-T30 III sits below the X-T50 as an entry-level mirrorless camera, with a compact retro design that includes a decent viewfinder and built-in flash.
The X2D II 100C is a premium 100MP photography-only camera with true end-to-end HDR capture, improved autofocus, and format-leading image stabilization.
The Panasonic Lumix S1 II is an incredibly powerful hybrid camera that's geared for video, with a partially stacked sensor, 6K 60p / 4K 120p recording, and highly effective image stabilization.
