D23 2019
We probably won't know anything until the week/day of the event.
WDI etc won't be previewed so you'll just need to wait for pictures from the day.
Good point! That will definitely be interesting to keep an eye on this year for sure.However, what may be different this year, in terms of previews, is that the Epcot Pin Event is before D23 this year. The WDI booth may not specifically say which items are for D23, but this year we might have clues. Unless, they don't come to Epcot because of preparation for D23...
