Unless you know something different then Delta managment as of a week ago no DC-9's are coming back in service. Most are being stripped for parts in the desert. Those going to the desert are no longer being stored in a airworthy condition. They are being stripped and scrapped. There are some pics you can find on the internet if you search. They are bringing 4 MD-88's back from the desert but Delta is sending some 757's to the desert coming up on heavy maintenance checks and NWA is sending some 757's and A320's to storage also facing heavy maintenance checks.
