Nikon working on two new 18 and 85mm tilt shift lenses?

There is a wild rumor that says that Nikon might be developing two new Tilt Shift lenses for the Z-mount: A 18mm and an 85mm lens. Not sure how reliable that rumor is but for sure the old 19mm T/S F-mount lens has been discontinued in Japan :(
