I have confirmed that the next Union Raid starts on 4/1 (Got info from Server) which leaves plenty of room for this reprint. Also, with that Light boosted gacha, I also think this event is confirmed to be next.

I also watch those banners and news direct links, however it seems that they have been locking them down recently and only allowing me to see whichever ones are currently out. As for Raids, there are other ways to get in and see when they start. Advents, I don't know right now.
