The No-Brainers for early launch window
- Zelda (it is known)
- Smash Bros 4 enhanced port
- Splatoon port or Splatoon 2
- Mario Maker NX
- A multiplayer party game showing possibilities
Likely within the launch window
- A 2D platform game (most likely Donkey Kong since I believe next full Mario game will be a 3D game for second push on christmas season)
- A "core" action game (new Platinum game/new Metroid)
- Another TecmoKoei collab (Hyrule/Fire Emblem Warriors or worst timeline: Metroid Warriors following up on Other M storyline instead of true Metroid)
- A niche series continuation (Luigi's Mansion 3 or F-Zero)
- A "casual" sim game (my bet is on new full Animal Crossing right there, alongside a mobile game for cross functionality)
There will be more Wii U ports since their development did cost a lot of money and some might profit from stronger hardware or a new enhanced audience, such as...
- Xenoblade Chronicles X
- Bayonetta 1/2
- Pokken
Games which will be announced early but release holiday 2017/2018
- new Mario 3D
- new Mario Kart
- new Fire Emblem with mobile game cross functionality
- new Monolith RPG
- new Pokémon with Pokémon Go cross functionality
- new Ubisoft collab (Rayman Legends 2 or less likely Beyond Good & Evil 2)
New Virtual Console will launch and hopefully we'll get a Wii level output going again instead of the Wii U barren schedule.
... yeah, this sounds like a wet Nintendo fanlist. Then again, I believe Nintendo will go all out on NX and since most of their core teams are on NX software for at least 2 years now, a lot on this list is not even unlikely (well, apart from my mentions of Metroid and F-Zero
). Solid mix of some surefire evergreens, some surprises, more third party spin off collabs and Wii U ports it will be, I guess.
