I will be very interested to see how they do this. We have a reservation at the Grand Californian checking in on June 23rd that predates this announcement. Originally we were not planning to go to the parks on the 23rd, just get settled in and hit the parks starting on the 24th. If we can get a reservation to SWGE on the 23rd, we may rethink this plan and try to get there earlier than originally planned (we are driving) and make the 23rd a park day.
