Another similarity to add to the list is that S4's villain will be different than past seasons. The past three main villains of Arrow and Flash has been all martial artists/fighters and speedsters respectively. Arrow S4 introduced a magic using villain, a departure of previous seasons. S4 of Flash will not have a speedster main villain next year, also breaking precedent.
