Nikon is rumored to be currently working on a new full frame mirrorless camera. Here is what I know so far:
- full frame camera
- mirrorless / mirrorless-styled
- the camera will be small (about the same size as the Olympus E-M1)
- no EVF
- regular F mount
- currently being field tested
- the official announcement is expected in late 2015 or early 2016
Another hint that in a way confirms this rumor is a this recently filed Nikon patent for a 28-80mm f/3.5-5.6 VR full frame mirrorless lens.
In interviews with AP and dpreview last year, Nikon executives said that a new large sensor mirrorless camera is a possibility in the future.
