In an interview with TechRadar a Nikon UK spokesperson said that they are not a broadcast company yet, but they are exploring video options for the future:
"We're not a broadcast company - yet. We're still listening and as our relationship between third parties grows, hopefully more features will be incorporated in the future."
In the past few months I have received some tips that Nikon indeed is considering to enter the pro video camera market. There were even rumors that Nikon was working very closely with RED. Another rumor indicated that Nikon showed a few top cinematographers a new full frame camera concept, specially designed for video.
At that point I would rate those rumors at 30% probability.
