I predict that we are going to see very odd numbers next year.
For Disney it's the first park that you visit in one day to "score" the visitor to that park. Until the opening of Carsland, DL always opened hours before DCA and the inferior offering of DCA led most of the people to enter DL first and then park hop to DCA during the day.
But being Carsland a priority in the morning to get a Fastpass before 9:00 (when they run out) and since the two park now open almost at the same hour we'll see a huge shift of people entering DCA before DL. So even if the crowd will not be substantially lower in DL during this year, we'll probably see a huge jump up of DCA and less visitors for DL, but due only to how Disney counts people.
