Okay, I figured it out and in very few words here is the outcome. I have both the Nikon D4 and D4s. Tagged/locked images on the card designated as the "primary" WILL NOT ingest into PM. It makes no difference if the card is XQD or CF. Therefore, if the XQD card has been designated as primary, the tagged images will ingest only from the secondary card which in this example is the CF card. If the CF card has been designated as primary then the tagged files can only be ingested from the XQD card which is the secondary card. The only other consideration that must be made is for those who shoot RAW + JPEG. I'm a RAW shooter therefore my camera is setup to write RAW files to the primary card and a BACKUP to the secondary card. Oh! I forgot to mention that now the XQD card has been designated as the secondary/backup card because of faster read times into PM. I hope that this makes sense!
