I'm quite late on this, since this review has been out since 24.12.2007, but I'll post this in absence of DPReview's review of the Nikon D3.

I like Bjørn's reviews but I'm really looking forward to Phil Askey's review of the Nikon D3, they are thorough to say the least.

In the meantime you may read the Nikon D3 preview at DPReview.
