Sooooooooo.....is there nothing for Q4 nintendo?
In no particular order they seem to be working on
Confirmed:Breath of the Wild 2
Metroid Prime 4
Pikmin 3: Deluxe
Detective Pikachu
Pokemon Snap
Bayonetta 3
Heavily rumored:Mario Remasters
Mario 3D World Deluxe
Mario Sports
Zelda game (possibly a remake or remaster)
Fire Emblem (2nd 3DS remake they were working on after Echoes)
Unknown Monolith Software game
Splatoon 3
Kirby
Rumored:Xenoblade Chronicles 3
Metroid
Donkey Kong spin-off
And then there's the opportunity to asset flip Mario Kart Tour into Mario Kart 9.
Considering BOTW was a launch game, I believe BOTW2 will be the next big release, either this fall or May 2021 or so... or the project has been completely reworked but if that's the case Nintendo would've announced it.
I'm definitely expecting the 3D Mario remasters to be out this holiday too if they exist. Metroid Prime 4 is the big wildcard for me. It could be pretty far along or it could be in development hell all over again.
Considering they want to be sure they can ship what they announce they probably won't confirm their full line-up until September and they could even announce the fall line-up piece by piece on Twitter over the next 2 months.
I wouldn't start to worry about Nintendo's fall line-up being sparse until late September. Nintendo always has their summer holiday leave in August. During the last month a number of studios including HAL Laboraties and IntSys moved to a new building too.
Also look out for September 13th as that is the date of the 35th anniversary of Super Mario.
Nvidia is working on DLSS 2.0 implementation for consoles, so expect news on a Switch Pro or Switch+ within the next 12 months or so as that will open the door to plenty of 3rd party games that could render at 540p and be AI upscaled to 1080p or render at 720p and be AI upscaled to better than native 4k.
