I have read the May and September requests regarding DNG conversion on ingest and want to say that this is a really important issue which I hope you will address in the 4.5 release. I am guessing you have been looking at Bridge in CS3. In any event, I plan to use DNG now as part of my workflow because I recently learned that I could save the Camera Raw settings to the DNG files without modifying my raw data destructively. It seems like a pretty good way to get both archiving and adjustments since I don't trust Nikon to support its RAW file format but Adobe has committed to maintaining DNG.
I long winded justification for using DNG but I don't want to give up on PM to do so. Any prospects on the horizon?
