I thought the same thing when Hogsmeade had two months of softs and seemingly everyone in Orlando who cared had been in (I was in there like four times). And yet it had a 6-hour line on its official opening day. Orlando is weird, and the thirst to be "first" -- even in name only -- is real.
Completely agree with your other points. I do wonder if this affects the AP upgrade timetable, or if Universal is concerned that will cannibalize Frequent Fear money.
