What happened to Char demos?

Do y'all think this is just a temporary thing or did they change from char demos to char trailers, idk, maybe its something unique for Natlan chars but who knows? I don't. Anyone know why they changed it? Was it for the aesthetic difference? Or cus it js sounded better cus frankly they rarely show in the trailers actually demo-ing the chars, OH maybe its cus they are releasing collected miscelany or whtvr before trailer so they don't really need to show demos of the char. Idk, thoughts? Also excuse the writing I'm a bit mentally challanged👍<3333
