Nikon Mirrorless Camera

DPReview has posted information from a recent Nikon interview.  They have confirmed the corporation is working on a new mirrorless system and even hinted it is geared toward the high end.  The latter thoughts come from a previous interview where they said they are focusing on the mid and high-end cameras.  Could it be Nikon is working on a professional quality mirrorless system?  Perhaps one which takes existing F Mount lenses.  Could it be?
