This post is purely speculative and I don't pretend to have any insider knowledge whatsoever. With all of the announcements made at D23 2017, many of which seemed to be geared towards major enhancements and/or additions that will ready in time for 2021, I'm wondering what big announcements are in store for 2019 and the 50th anniversary in 2021? I could envision D23 2019 being focused on major 50th anniversary event and entertainment announcements. By the time 2021 rolls around, all 4 of the existing theme parks will have had major additions/expansions over the preceding decade (or so). So wouldn't the 50th anniversary be the perfect time to announce a 5th gate? Just curious if others think this could happen or is this just my wishful thinking?
