I currently have a D200 and have been waiting very patiently for the D400 since I am not a pro and don't have to have every incremental change. I definitely have gotten my money's worth from the D200 and plan to keep using it, but the low light performance has been a little frustrating for me. The D7000 looks really compelling but that leaves me wondering what the D400 will offer when it comes out, other than heavier construction and ergonomics. The D7000 offers a very compelling upgrade, so the D400 must be crazy good to make people want to move up. Any thoughts as to how? The other question is WHEN it will come out with the D4... I guess next spring.
