clearly they're waiting for Three Hopes to come out so they can shamelessly advertise their next Fire Emblem game, like Echoes of the Binding Blade or something. Look, it's not a complete Direct experience if I don't disappoint myself for a Fire Emblem announcement, please understand.
But that's fine, honestly. If the Direct is the 29th, it'd be nice if they communicated that there'll be a direct late this month before fans go in meltdown mode, but what you can you do? And there's sense in keeping everything away from the bulk of announcements happening this week.
