I would take a look at it, but that's pretty meaningless. I'm happy with 5e, it brought back what I loved about TSR versions of D&D and combined it with the rules fixes (i.e. no more THAC0) and organization of 3e. I think the 2024 update was necessary even if I don't care for all the changes. But radically different? At a certain point it's just a different game and I learned with 4e that there are certain things I want out of my D&D game. If I want radically different I'll find a different game.
The problem with the hypothetical is, of course, that everyone answering that they would jump on the new version because it's so different will have unique ideas of what that means. It's a pretty meaningless question to ask. Would I like a flying car? Sure. Is it going to cost 10 times as much as my current car, do I need to get a license, is it safer, I live in the upper Midwest can it handle weather, will it fit in my garage, how much will it cost to run and maintain? All of those things change my decision from "it sounds cool" to "absolutely not". Same with any hypothetical game. Seems like the people who complain about D&D the loudest want a game I don't.
