In addition to the D7000, the new 200mm f/2 lens and the P7000, Nikon may announce a new Speedlight and a second lens before Photokina. I do not have any details, but the flash could be a replacement of the SB-600 (you probably remember those SB-600 being discontinued reports) but it could also be a replacement of the SB-400. I do not think that the SB-900 will be replaced, since it was announced 2 years ago (SB-400 and SB-600 were announced 6 years ago).
The second lens will be a tough guess. According to my initial list of expected lenses in 2010 from February, the choices are for a new DX zoom that will go with the new D7000, a new AF-S 35mm f/1.4 or the long expected 80-400mm replacement.
If Nikon announces 2 more lenses, this will bring the total lenses for 2010 to nine, which is a new record. There could also be another announcement after Photokina (around November/December).
