Okay, I think I get more of your frustration, but I would argue Crawford isn't being disengenious or playing a semantics game. He is telling you exactly what you want to know.
The books coming out in 2024 are new "editions" or new versions of the Core Rule Books from 2014. But they are not a new edition of the game of Dungeons and Dragons. I know you currently think that is a distinction without purpose, but to me that is very clear. The 2024 books will still work with Curse of Strahd, with Radiant Citadel, with Fizban's Treasury of Dragons. They even work with Tasha's, though to a lesser extent, because the Artificer isn't being republished yet, but they clearly expect people to keep using it.
Now, take a moment and think of other edition changes of the game itself. The big ones. I have copies of things like The Complete Divine from 3.5 and it is completely and totally unusable in 4e games or 5e games. I can't run the Red Hand of Doom in a 4e game, I might maybe be able to heavily modify it to run in a 5e game, but at best I'm just going to be taking the plot points and adjusting everything else. Same with some of the 4e material. You couldn't run Kingdom of the Ghouls from 4e or Prince of Undeath with MASSIVE edits, because those games expect you to be over level 20. The 4e Martial Power book is also just completely unusable in 3rd edition or 5e games, none of the rules work.
As they get closer to the release, are they going to be hyping the release? Yes, obviously. Just like the newest Samsung Galaxy S23 is getting hyped to phone users and the newest 2024 Ford Ranger is getting hyped to Ford Truck buyers. But that isn't disingenuous or lying to you, that's just selling a new product.
Do you need these revised rulebooks to keep playing DnD and published adventures? No, just like you never needed Xanathar's or Tasha's or Volo's. Do you need these revised rulebooks to have all the newest stuff that the community is going to start adopting as standard? Probably yes, just like with Xanathar's or Tasha's or Volo's.
