Looks like Nikon's mirrorless entry is getting closer to reality. A couple posts over on Nikon Rumors with actual pictures of the upcoming mount seem to confirm that it will have a sensor with about a 2.6x crop. Somewhere between m4/3 and the Pentax Q. This figures, of course, because I just decided to jump all in to micro four thirds about a month ago! Then again, it will be interesting to see what kind of noise issues they will have given the smaller sensor. If they keep the megapixels reasonable (unlikely), perhaps it will be pretty good?
