The new arc, which was announced at New York Comic Con, will pit Barry Allen against the original Wally West to find out who can lay claim to the title of Greatest Scarlet Speedster. Wally spent quite a bit of time absent from the DCU, but has since returned in the Rebirth event. What that time out of sync might have done to his speed remains to be fully explored.
