I hope the direct will be on the 1st of September.
The week of the 8th (like
@CypressFX said) is the week of Splatoon 3. So I don't expect a direct there, then the week after there is TGS so I doubt they'll wait more. Also there hasn't been a general direct in June, so going from early February to late September seems kinda weird to me.
My bet is on the 1st. Maybe even the 31st of August (the midnight between the 31st and the 1st here).
As for my predictions:
1. What I want, and I'm kinda sure I'll get:
- the new Fire Emblem.
- a title and a BIG TRAILER for BotW2. I'm not sure about a release date tho.
- a new game from Team Asano (unfortunately not Bravely related).
2. What I don't care about, but I think will be there:
- Switch Sports DLC
- Splatoon 3 last trailer
- Metroid Prime HD remaster
3. What I would love to see, but I doubt will be there:
- Ace Attorney 7 / The Great Ace Attorney 3 / Ace Attorney Investigations duology (<- from less hype to most hype lol)
- a new Professor Layton (even I know that I will never see this)
- a new 2D Zelda (I really hope this will be on Switch sooner or later)
- Bravely Default. Anything.
- Kid Icarus.
