I think this is a great time to expand the body collections. Many for financial reasons are just selling at fire sale rates. I for one will be keeping my D2Xs and D200's. I shoot landscapes and wildlife and thats where DX fomat and the 2X crop really shines.(The longer telephotos.)I will be using the D300 with a newly aquired 24-70 f/2.8. I am sending the D200 to Life Pixels for the IR conversion and dedicate my 17-55 f2.8 to the IR camera. See ,you can find a spot for just about everything if you look hard enough. No D3 in my future as it is not the field camera for me. Now when the D3X comes out that may be another story,something may have to go.
