In addition to the P100 and L110, Nikon will also announce Coolpix S3000 and Coolpix S8000 cameras. I am still expecting more details in the next few days.
I am sorry I keep bringing up compact cameras, but I think this is what the February 3rd announcement will be about. I now strongly believe that there will be another announcement in the week after February 3rd (or maybe the week before?) that will bring the good stuff. I do not think the February 3rd date will be for Coolpix cameras and DSLRs/lenses at the same time. Last year, Nikon first announced the D300s and D3000 (July 30th) and the week after (August 4th) four Coolpix cameras were released.
