Chasseurs d'Images just published a test of the definitive D70. They gave it 5/5 on just about everything except use in the studio (damn). The only big surprise is that its new flash system makes it incompatible with previous Nikon flashes, including the SB80 (damn).

It looks like a real winner with the 18-55. If I were you I'd wait till there have been more tests and people have been able to compare it with the 10D.
