Nikon has scheduled an official press release for January 8, 2013, which is the starting date of the 2013 CES show. In addition to the new Nikon 1 J3 and S1 mirrorless cameras, I believe Nikon will also announce the availability of two new 1 Nikkor lenses: 1 Nikkor 10-100mm f/4-5.6 and 1 Nikkor 6.7-13mm f/3.5-5.6. The development of those two lenses (together with the 1 Nikkor 32mm f/1.2) were announced back in October and Nikon is expected to start shipping them early next year. There is still no word on the new 800mm f/5.6 lens that was introduced back in July, 2012.
