Another Nikon announcement is coming soon: the latest rumors I received today indicate that Nikon will soon announce new product(s) (could be as early as this week). I still cannot confirm the exact date, but the D800/E replacement was rumored to be announced this month. Another possibility is the new Coolpix camera with 1" sensor.
I am trying to get the exact announcement date. If you have any information, you can always contact me anonymously here.
