I’m still holding out for the next generation D700 which should be on shelves by the end of the year, of course there’s no guarantee on that.
(Here’s some info on the new D300s- http://www.dpreview.com/news/0907/09073007nikond300s.asp)

For the most part, it seems like the main improvement on the 300s is that it adds HD video capability to the 300. There are a few other additions, but that’s the main selling point, and with the direction journalism is going, it’s a pretty big selling point these days. And it looks like that will be the main addition to the D700x as well. My good friend and colleague, Jason Motlagh (http://88zero.com/Motlagh) has been working overseas continually for awhile now and has had great success selling full media packages of stories- article, photos, video. In this tough market in a threatened industry, the more you can offer a client, the more eager they’ll be to work with you. In that respect, this new upgrade adding video could be a big asset to many photojournalists. Why do I recommend holding out for the D700x upgrade if you’re looking for a new pro-level DSLR? From my time using both cameras (300 and 700), the D700′s biggest advantage is how its full frame sensor results in getting wider angle shots, which are so important in photojournalism, especially in environmental portraits (people active in their environment). The other big advantage of the 700 over the 300 platform is that again due to a larger sensor, the pixels aren’t as crowded on the sensor, meaning the images show more detail and have less noise at higher ISO’s. I’ve shot very usable images at 2500 ISO in low light that resemble images shot at 400 ISO with my D200. God bless technology- it has made our job so much easier.
