The Nikon D800 book triggered a series of new tips and leads. Those are the most reliable rumors I received so far (please note that because a potential announcement is months away, some of the specs and/or release dates may change):
- The Nikon D700 replacement will be called D800, it will come with a new 24 MP sensor, new AF system, full HD, same noise (ISO) performance like the D700. The announcement should be in Summer of 2011 (which is later then what the D800 book suggested). This camera is aimed to be a direct competitor of the Canon 5D MarkII.
- The successor of the D3s will be called D4 and it will have 16 MP, 11 fps, full HD, new AF system and the same noise (ISO) performance like the D3s. The Nikon D4 should be announced in Spring of 2011. The D4x will follow with a 34MP sensor.
If true, this line up will indicate that Nikon will move away from the D3/mini D3 (D700) DSLR lines and create two more distinguished camera products. The D700 probably did cannibalize some of the D3 sales which (I guess) triggered that decision (otherwise they could continue to use the D3s/4 sensor in a D700 body).
No word on a D300s replacement yet.
