If you have something to shoot today or next month, get something that exists today. See my page on obsolescence for more.
Moving downmarket, it will come in silver paint as well as professional black. Please get the black.
It will replace the D40. It's got a somewhat newer, cleaner looking body and weighs even less.
I expect the D60 to sell for about $599 for the body alone.
It uses the modern EN-EL3e battery.
The monitor is a new 2.7" LCD.
I expect it to the same 10MP sensor as the D80 (standard DX sensor size) and 2.5 FPS. Image quality will match the D80 and D200, with a lower price and a few less features.
Be sure to order one as soon as it's announced to get it for Christmas. I find Ritz takes orders first the day it's announced, then Adorama a little later in the day, and Amazon usually takes weeks until they accept orders.
