As noted on the Toonami Faithful podcast, the fifth season of Samurai Jack is an [adult swim] original show, so it's likely that they'll probably expand the block again and air it at 11:00 PM in order to give it the best timeslot possible. If not, then as mentioned below, it could end up replacing Dragon Ball Z Kai when that show ends, assuming Kai doesn't continue on into the Buu saga.
