This Nikon rumor is from an Asian forum member with good previous track record (I briefly covered that rumor last week, but now I have some more details):
Supposedly, those are all scheduled for summer release. The DX body is probably going to be the D90 replacement, the FX body will be a D700 replacement or a new FX line. Initially, the 35mm f/1.4 lens was suppose to be announced in 2011, but as I mentioned already the new Sigma 85mm f/1.4 has caused some “waves” at Nikon and maybe they will do some last moment adjustments.
There have already been some rumors in the past for the 24-105mm and the 100-500 mm lenses.
