Nikon has announced a service modification for the D3 that more than doubles the number of frames that can be shot in a single burst. The number of FX Format 14-bit Lossless Compressed NEFs, for example, jumps from 16 to 36, and most other file format options see a similar increase. Nikon USA, locales in Europe and perhaps other regions too are already accepting customer cameras for the modification.*UPDATED*
