After long criticism that the Z-mount system was comprised of pro-level cameras with kit-level lenses, Nikon will answer with a 50mm f/1.2 and a 14-24mm f/2.8. Specs can be seen over at Nikon Rumors.

The wide zoom announcement may be what precipitated recent inspecific Canon leaks of a wide f/1.4 zoom, not anticipated to hit market in the short-term.
