The 2024 books are out and people have bought them. They don't need to peddle that line any more.
The only reason to not re-release their greatest hits under 2024 revamps is to avoid upsetting people whose money they already got years ago. And by putting out these new books, all of the new players -- who again, are large in number -- will get to hear that "one of the best-loved D&D books is coming back!" which is a great message to have out there, floating around the internet.
I don't think we're going to see most 2014 books re-released -- I don't think anyone's clamoring from Out of the Abyss Once Again -- but I would definitely expect Ravenloft for sure and possibly seeing Tales from the Yawning Portal stripped for parts and re-released in more substantial forms for 2024.
