Seeing no evidence of the overnight at all (not a single photo, have you?), I'm feeling like that was just a rumor.
If the stores haven't changed at all or don't have any black curtains dangling right now, it probably isn't happening.
I agree. Apple stores in the Eastern, Central, and even Mountain time zones have now been open for at least an hour. I haven't seen anything to indicate that there have been any store changes in any of those stores.
