I received some new information from a good source:
- The Nikon D7000 replacement should be announced before April, 2013 with a 24MP sensor, 100-6400 ISO range and a form factor similar to the D600, but in a smaller body.
- Nikon will announce more new Coolpix cameras, including a P310 replacement that will add RAW files and WU-1a support for wireless transfer. The P310 was announced in January 2012 and currently sells for a little over $200. In addition to the P7700, the P310 is the only hope for a "serious" Nikon Coolpix compact camera.
