While I think your point about the future accessibility of edited NEF files being better with LR than NX2, PM does offer a solution. From within PM, I can generate both jpgs and tiff files based upon the NX2 edited NEFs. Admittedly, the quality of these files are probably lower because they are generated, I think, from the updated embedded jpg preview that NX2 writes when saving after an edit. I am not sure how NX2 generates tiffs but I have done some "pixel peeping" comparing PM and NX2 generated jpgs and tiffs. Unless one was viewing images at 100% or making very large prints I doubt anyone would see a difference. I would appreciate someone else's input with more knowledge than I on how the image quality compares when generating tiffs from within NX2 and those generated from PM on NX2 edited files.
