I mean, it's not technically an "announcement" but i consider SNW in Osaka to be another look into the new gate. After all, i believe we can all agree here that similar to SW:GE, the orlando and japan versions of these lands will be almost identical with only slight changes.
So, when it comes to the smaller tidbits of information about SNW. (Food, Shops, Interior Details, Etc) I think we'll learn a lot when Spring 2020 rolls around.
