I just wanted to comment that at CLAMP Exhibition currently being held in Tokyo, the room dedicated to CLAMP works has D&D description as "on hiatus", same as in xxxHOLiC Rei and of course X (as of July 2024) Also, neither LD or D&D has been announced for the Clamp Premium Collection yet.
My bet is that someday D&D will make a comeback and an anime adaptation at the same time so when the anime ends, the manga also ends serialization. BL now sells like crazy in Japan, so it would be a good oportunity.
