That's not going to happen. Literally no-one has ever complained about that.I'm worried about having to listen to how WotC ruined the setting because they gave people permission to use it in whatever way was fun for them.
What's much more likely to happen is that WotC eliminates a large number of ways people could use it simply by changing the lore and rules of the setting in such a way that they might as well have not bought it, and that they have to homebrew together an entirely different version.
But what's even more likely to happen is WotC doesn't do Dark Sun, they do Spelljammer. Which is virtually unsinkable.
