Nikon Rumors are reporting that there are two upcoming announcements from Nikon:

• 17th August 2010 - For Nikon's usual mid-year CoolPix refresh. We'd like to see a Canon G11 killer, but expect that this model has been pushed back (or even cancelled).
  
  
• 19th August 2010 - For the expected D3000 replacement (rumors have named it the D3100, we remain to be convinced of the model number) and some lenses. The lenses should be an 85/1.4 replacement, a 24-120/4 VR (FX), a DX 55-300/4.5-5.6 VR, and one other than sounds odd if true - an FX 18-200/3.5-5.6 VR.

Time will tell, and I'm sure there will be more leaks coming before the middle of August. Unfortunately we're not expecting to see a D700 replacement this time round - though we hope that (and the D90 replacement) may be ready for Photokina in September.
