I don't think they are going to a freestyle dining style. Rather, at least in the tests they conducted on one of their ships, they have basically set up four times for dinner. In one dining room the early seating may be at, say, 6pm while in the other dining room it is at 6:30. Late seating in the first dining room would then be at perhaps 8:15 and in the other 8:45. Not sure of the exact times but that is sort of the idea. Eliminates some of the crowding that occurs when both dining rooms operate on the same schedule and may also help the kitchen (if it is shared by both dining rooms) handle the volume of orders. Show schedules would be arranged to accommodate the new dining schedules. Perhaps more knowledgeable Carnival cruisers can elaborate on the new system and how well it works.
