The problem with that train of thought is that it’s actually TOO early, for a specific reason. That scheduled maintenance is also on the 28th for Japan. Since their time is 14 hours later than EST, the maintenance lands from 2:50 pm to 4:30 pm the same day. The thing is, Byleth’s Japanese release date isn’t on the 28th… it’s on the 29th.
