video. Short videos of the family might be treasured keepers later on. Of course if you are looking at used D7000s you would also be able to get video capability that way. If you are just into landscapes and still shots of the family, I woud keep the D200 and go for some better glass. The point with the better glass is that it can always be used later on with the Nikon bodies. However, if you go with non-AFS lenses, e.g., 80-200, you will need a body with an internal motor like your D200 has. The D300s as well as the D7000 fill that bill.
