frankly, when spending this kind of money on a camera - and think of the money spent for lenses - a company like Nikon should show greater sensitivity to an issue that compromises the quality of that camera. I have decided not to purchase a D600 to replace my D7000 until i am totally assured that the sensor dust/oil issue has been resolved, once and for all. I had contemplated selling my 7000 and lenses, taking the loss, and moving to Canon . . . but the lost money would be significant and i am not comfortable with that. So, i will wait and see what happens. However, Nikon shows little concern for their customers when they fail to resolve an issue that seems widespread. I wrote "seems widespread" because no one knows the proportion of cameras coming back for repair, or were returned because of the spots/dirt/oil. Just think how many of us are out there who have decided to wait and see what happens to this problem before we make a purchase. How much is that costing Nikon, now and in future sales? Tolerating poor quality control is a very bad corporate mistake that can come back to haunt a company. Nikon should know that.
