Notes:

I might as well post my predictions on all this stuff while I'm at it:
Something Disappointing: Guaranteed.
Detective Pikachu: It'd only really matter if they actually got Danny DeVito to voice him.
Pokken: Guaranteed. It's almost here, after all.
Pikmin 4: Maybe?
Federation Force: NO. NEVER AGAIN.
Post-Direct stuff: Maybe-to-guaranteed.
amiibo: Guaranteed.
FE Fates EU: Maybe?
Bill Trinen: He'll be there, but I don't know how silly he'll get.
Nindies: Guaranteed.
Paper Mario Wii U: Calling it now: It's Sticker Star 2.
5 sec. of Zelda U: Guaranteed.
No Smash DLC: Sakurai said Bayonetta was the last one, so this seems really unnecessary, unless they make more stages and Mii costumes, at least.
Star Fox Zero: Don't delay it. Please.
Third-party: HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA
GCVC: I honestly don't know.
Reggie memes: Maybe-to-guaranteed.
Mother 3 VC: HAHAHAHAHAHAHAHAHAHAHAHA-here's a Fire Reggie amiibo.
Pokemon G7: Guaranteed. Maybe we'll get a first look at the starters, too.
E3 tease: Maybe.
Splatoon paid DLC: Oh, God, no. Please, no. Just give us the Squid Sister amiibos and I'll be fine.
Bayonetta 3: No chance in hell (unfortunately).
SMT vs. FE: Man, what the hell happened with this game? I don't know if I want it now.
Sakurai's new project: Maybe?
Something new: If the gap between Pikmin and Splatoon is anything to go by, we should probably expect a new IP sometime either in or after 2027.
