There is a low chance that new Coolpix cameras will be announced tonight (Monday, US Eastern time) and the Nikon D3100 plus the four lenses on Wednesday night. The second option is that everything will be announced together on Wednesday night (around midnight, US Eastern time).
The German magazine "Foto Digital" leak from last week had only two Coolpix cameras - the Nikon Coolpix S1100pj and the Nikon Coolpix S5100. Not sure why the rumored Nikon Coolpix P7000 was not covered in that article. Maybe they will announced it at a later date? I don't know.
