This article doesn't appear very credible. It starts out by saying that Nikon will be coming out with a D300s in 2010. Sorry but the D300s has been out for several months. No way a D4 is coming in 2010 since Nikon just introduced the D3s.
The D7oos is what I've been waiting for. it does seem to be the natural progression of the smaller FF camera. Nikon needs something to compete with the Canon D5 II.
