Yeah I'm pretty sure ALL of next week. That's what an employee told me from a meeting he went to. He told me that was a "guarantee."
That's mainly why you won't see any softs. If you really want to see Potter again and can't make it to previews, you'll have to wait a week and a half to see it. After that, it should be similar to the first soft where it opened the last three hours. So yeah, don't go next week unless you don't mind missing Potter.
Oh, by the way, I heard the Quittich goggles finally came in during EP. Did the domes seem improved with them on?
