No. Because Haytham's conception would automatically make the Animus stop following Edward, and jump to Haytham as the next ancestor.

Ed died when Haytham was already born, so we won't see his death. Unless they do something idiotic like making people play 8 year old Haytham at the very end of the game, which I doubt.
