I hope so. I have the money for a D4 or D800, but can't justify dumping $6,000 on a camera. I am not a professional! I love the idea of a D800 compared to a D700 at similar prices. Now that the D700 will be expected to be $2,200 I will have to evaluate some more. I still think I will go the D800 route, but I am waiting on some hands on reviews. I have had the D200 since it was made available and see no reason why it won't work for me another 3 or 4 months.
