Not a clue. I do not remember seeing Nikon drop a price two months after issue of a new model. I bought my D200 for $599 when the D300 was brought out and I couldn't have been happier, but the D200 had been out a LONG time already. I am mad about the D600 $ drop but no law prevents this. I paid $2100 for the body and now for $100 less could get $700 in additional products. Sigh.
