On Twitter WotC's Christopher Perkins clarified queries about his new role after it was revealed that the 2024 Dungeon Master's Guide would be his last book as Product Lead--he is now D&D's Creative Director, which looks like a broader, more overview-type job. Creative Director was the role that Mike Mearls held until 2018 before moving over the Magic: The Gathering, and George Krstic held a similarly named role until August this year.
Not true. I was a Game Design Architect. Now I’m the Creative Director, which is a more “behind the scenes” gig that lets me play quietly in a bunch of different sandboxes. #wotcstaff
