Nikon filed a patent in Japan for 70-300mm f/4-5.6 lens designed for a camera with 1" sensor (Nikon 1)/ The FX equivalent of this lens will be 190-810mm. The lens design consists of 20 elements in 13 groups including 6 ED elements.
Another patent describes a new type of adapter what will add image stabilization (VR) to existing lenses while maintaining AF.
Next patent from Nikon Japan describes phase detection AF with no image quality degradation.
How about a SLR camera that doesn't "black out" when taking a picture? Nikon got a patent for that as well:
"There are many needs of the single-lens reflex camera provided with the optical view finder which can observe a motion of a raw object. A common single-lens reflex camera arranges a movable mirror between a lens and an image sensor, incident light is reflected in the optical view finder side at the time of object observation, and it has structure which has been over mechanically about the movable mirror and projects incident light on an image sensor at the time of exposure."
