Update: this rumor got busted.
I am not sure if those specs are the real deal - I found them on dpreview:
An APS-C sized 12.2 megapixel cmos sensor with liveview capabilities.
Continuous shooting rated at 4 fps for 38 large/fine jpegs.
The same viewfinder as the d80.
A new 3" LCD display with 230,000 pixels (same as Nikon coolpix s52c)
anti-dust facilities (sensor shake only, no airflow control from the d60)
New Expeed processing. (i don't see how that will help)
ISO sensitivity same as d80 (100-1600+3200),But lower noise.
Liveview system identical to d300,d700,d3.
In camera retouching.
Same 3d color matrix metering II (420 pixel sensor)
The Nikon d90 may also be sold with a new dx lens the 18-105 vr lens
the price will be around 1300$ us with that kit.
Should I add a poll?
