According to previous rumors, Nikon will announce their first full frame mirrorless camera and DX mirrorless camera in 2018. Famous Nikon Photographer Thom Hogan bets that Nikon is going to announce full frame mirrorless camera in February at CP+ Show in Japan.
From Thom Hogan:
Still, we’re close. At least at the camera level. I expect Nikon to announce their new mirrorless system at CP+, which for 2018 begins with the month of March. I expect Nikon to have both DX and FX mirrorless options by the time Photokina rolls around next fall.
