After talking to several sources, nobody could confirm the announcement of the D7000 replacement next week. The lack of leaked images and detailed specifications also makes me think that either Nikon has gone completely underground with the new camera, or the D7100 will just not happen next week.
In my post yesterday I forgot to mention the second possibility for the upcoming press event: few weeks ago I reported that Nikon will also be announcing a Coolpix P310 replacement with RAW and WU-1a support. A new compact camera with a larger sensor is also a possibility - maybe with the 1" sensor from the Nikon 1 line.
So this is where we stand for now - either a D7000 replacement or a new high-end Coolpix camera(s) for next week.
