"And we basically saw that with last Switch Mini Direct, short Direct without big or new announcements, all news were ports/remasters and updates/DLCs, with only one new game announcement that's actually smaller game (Mario Tennis)."
We didn't get big or more new announcements, because they don't exist. Not because Nintendo was holding them back.
Unlike other Mini Directs, this one was a worldwide broadcast and was not game-specific Direct... just like your regular Nintendo Direct.
If we look at the 1st half schedule, you'll see that they keep their m.o. of one big title per month, at least.
And if you try to fill June's empty place with Hyrule Warriors, the first half is pretty much booked.
As i told you in another thread, this Mini Direct was different and you can't act like it wasn't.
