Eric, although I probably have only a 1/4 the number of images as you, I share the workflow concerns and abandoning a streamlined "NEF" centric workflow with PM/NX2. However, I find myself increasingly using other tools like NIK software which throw me into a TIFF workflow. So I either minimize the use of new PP tools available or consider a workflow based upon Lightroom or Aperture. But that would then force me to confront what to do my Edited NEF library. I wonder how others have approached the migration? Am I also correct in assuming any edits in Lightroom would not be available for preview in PM?
