Yes I read that
Don't believe it because it doesn't really make any sense to me. Wanda's brother JUST died last year, it wouldn't really "mean" anything for her to die right after him. Also Steve dying doesn't make sense either, Bucky at this point being named Captain America would be absolutely laughable after spending the entire movie with him as a fugitive and T'Challa coming for his ass. It also wouldn't feel "earned" for him or Sam at this point to inherit the title.
But
Why do you think they made a point to show Crossbones still being alive at the end of Civil War? He's the one who shoots Cap in the head in the Civil War storyline in the comic, and Bucky becomes the new Captain America.
