To say Nikon has been conservative with mirrorless cameras would be an understatement. While most of its rivals have embraced mirrorless (even a cautious company like Canon takes them seriously), Nikon's efforts have been timid at best -- the 1 series is closer to point-and-shoots in spirit than a DSLR replacement. Thankfully, it's mending its ways. In an interview with Xitek, company R&D manager Tetsuro Goto says that any new Nikon mirrorless camera "must" be full-frame. Given that the firm's president has already said that a mirrorless camera is in the works, it's clear that this upcoming model will come with a giant sensor.
