There are supposed to be announcements every day starting tomorrow, make your guesses of what they'll be each day, and we can see who was closest at the end of the week. Here's mine:

22nd: general news, Go and SwSh events
23rd: Snap news update, maybe Sleep too.
24th: Unite day, release date and gameplay
25th: main direct, DP remakes and Pikachu gift reminder
26th: whatever Legends is and any other miscellaneous news that wasn't on the 23rd
27th: Concert and maybe another gift/event
