New Nikon patents: Nikkor 52mm f/0.9 and 36mm f/1.2 full frame mirrorless lenses

Nikon 52mm f/0.9 full frame mirrorless lens Nikon 36mm f/1.2 full frame mirrorless lens Nikon has new patents filed in Japan for a  52mm f/0.9 and 36mm f/1.2 full frame mirrorless lenses: Nikon 52mm f/0.9 full frame mirrorless lens f = 51.60 (focal length) FNo = 0.91 (aperture) ω = 46.19 (half angle of view) Y = 21.63 (image height) TL = 256.8 (total length) BF = 18.225 (backfocus) Nikon 36mm f/1.2 full frame mirrorless lens f = 36.00 (focal length) FNo = 1.27 (aperture) ω = 31.0 (half angle of view) Y = 20.94 (image height) TL = 159.500 (total length) BF = 21.673 (backfocus) Nikon has already filed several patents for full frame mirrorless lenses in the past. Patents are no guarantee for future products, but I think everything so far  points to a new full frame mirrorless camera with a new mount that can accommodate a 50mm f/0.9 lens.
