Nikon Patents 100mm F/1.4

This beast appears to be targeting the Sigma 105mm F/1.4 rather than your typical OEM 100mm macro lens. The Japanese blog An Image on a Sensor dug up this recently-awarded Japanese patent over the weekend. It was filed originally in 2019, clearly designed for the Z-mount.

When Nikon last updated it len roadmap in November 2020, it then added a 105mm “Micro” prime to its S line of lenses, which had not previously been among its development priorities.
