I'd be very, very shocked if Splatoon 3 came out in Q1. I don't even expect to see it in this Direct.
The way i see it, is more so in that it's a game that hasn't been featured since it's initial reveal; and should be through a large stretch of it's development (As it did get announced in March). I see February, but I can see it delayed to March or April.
My predictions
- DK 3D Platformer announced
- New Kirby Game
- Final Smash Character trailer
- RE7 (it's already on the switch in Japan)
- Batman Arkham Trilogy
- Animal Crossing Mega Update
- N64 Online + N64 Controller
- Direct ends with Mario Kart 9 or first proper look at Metroid Prime 4
Forgot to put NSO here, but I'll add further.
NSO Regular - Game Boy is added for Free
NSO+ - Nintendo 64, Themes. Upcharge of NSO, around 10-12 dollars per year; and will be updated with new titles as often as NSO Regular.
